Five clinical judgment questions with answers
Cover the key. Write the first action. Then open the rationale and name why the other choices fail.
Question 1
What signs and symptoms most likely prompted this patient to initially seek care?
A. Malaise and fatigue
B. Severe diarrhea
C. Intermittent fever
D. Dizziness and confusion
Show answer and rationale
Correct answer: B — Severe diarrhea
The correct answer is B: Severe diarrhea. A patient who has recently returned from a trip to Nepal with a nongovernmental organization and is seeking care for amebiasis would most likely have been prompted by the symptom of severe diarrhea. Amebiasis is an infection caused by the parasite Entamoeba histolytica, commonly transmitted through contaminated food or water sources in developing countries like Nepal. The hallmark symptom of amebiasis is dysentery, which is characterized by severe diarrhea with blood or mucus in the stool. Malaise and fatigue (choice A) are nonspecific symptoms that may accompany many illnesses and are not specific to amebiasis. Intermittent fever (choice C) is not a typical presenting symptom of amebiasis, which primarily manifests with gastrointestinal symptoms. Dizziness and confusion (choice D) are also not typical symptoms associated with amebiasis.
Question 2
What is the role of oxytocin in childbirth?
A. Inhibit uterine contractions
B. Stimulate uterine contractions
C. Increase milk production
D. Prepare the cervix for dilation
Show answer and rationale
Correct answer: B — Stimulate uterine contractions
The correct answer is B: Stimulate uterine contractions. Oxytocin is a hormone that plays a key role in initiating and maintaining labor by stimulating uterine contractions. It acts on the smooth muscles of the uterus to promote the rhythmic contractions necessary for childbirth. Oxytocin also helps with the ejection of milk during breastfeeding but its primary role in childbirth is to stimulate uterine contractions.
Incorrect choices:
A: Inhibit uterine contractions - This is incorrect as oxytocin actually stimulates, not inhibits, uterine contractions.
C: Increase milk production - While oxytocin does play a role in milk ejection during breastfeeding, its primary role in childbirth is to stimulate uterine contractions.
D: Prepare the cervix for dilation - While oxytocin may contribute to cervical dilation during labor, its primary role is in stimulating uterine contractions.
Question 3
Antigenic variation is used by bacteria to:
A. evade host immune responses
B. increase antibiotic susceptibility
C. increase peptidoglycan synthesis
D. enhance motility
Show answer and rationale
Correct answer: A — evade host immune responses
The correct answer is A: evade host immune responses. Antigenic variation allows bacteria to change their surface antigens, making it difficult for the host immune system to recognize and attack them effectively. This enhances the bacteria's ability to evade immune responses and establish infection.
B: Increase antibiotic susceptibility is incorrect because antigenic variation does not directly impact the susceptibility of bacteria to antibiotics.
C: Increase peptidoglycan synthesis is incorrect because antigenic variation is not related to the synthesis of peptidoglycan, which is a major component of the bacterial cell wall.
D: Enhance motility is incorrect because antigenic variation does not directly affect the motility of bacteria.
In summary, antigenic variation in bacteria primarily serves to help them evade host immune responses, making option A the correct answer.
Question 4
The nurse is making a plan of care for a patient who is in the first 24-hour period past a cesarean delivery. Which interventions will the nurse include in regards to medications? Select all that apply.
A. Continue a daily stool softener.
B. Manage pain with morphine.
C. Ensure the availability of naloxone.
D. Provide prophylaxis antibiotics.
Show answer and rationale
Correct answer: C — Ensure the availability of naloxone.
The correct answer is C: Ensure the availability of naloxone. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose, which could occur if the patient is receiving morphine for pain management post-cesarean delivery. It is essential to have naloxone readily available to counteract any potential opioid-related respiratory depression.
A: Continuing a daily stool softener is not directly related to medications typically given post-cesarean delivery and is not a priority in the immediate post-operative period.
B: Managing pain with morphine is a common practice post-cesarean delivery, but the focus here is on the intervention related to medication safety, which is ensuring naloxone availability.
D: Providing prophylactic antibiotics is important post-cesarean delivery to prevent infection but is not directly related to medication safety in this scenario.
Question 5
If a radioimmunoassay is properly conducted and the amount of radioactive hormone bound to antibody is low, this would indicate which of the following?
A. Plasma levels of endogenous hormone are high
B. Plasma levels of endogenous hormone are low
C. More antibody is needed
D. Less radioactive hormone is needed
Show answer and rationale
Correct answer: A — Plasma levels of endogenous hormone are high
The correct answer is A: Plasma levels of endogenous hormone are high. When the amount of radioactive hormone bound to the antibody is low in a radioimmunoassay, it indicates that there is a high concentration of non-radioactive, endogenous hormone present in the sample competing for binding sites on the antibody. This competition results in fewer radioactive hormones binding to the antibody. Therefore, the low radioactive hormone binding suggests an abundance of non-radioactive hormone in the sample.
Choice B is incorrect because low levels of radioactive hormone binding do not indicate low plasma levels of endogenous hormone. Choice C is incorrect as more antibody wouldn't affect the binding of radioactive hormone if endogenous hormone levels are high. Choice D is incorrect because the amount of radioactive hormone needed is not related to the binding observed in the assay.

Question 6
When assessing a prenatal client at follow-up prenatal visits during the second trimester, the nurse should anticipate which assessments to be performed at each visit? Select all that apply.
A. Cervical examination
B. Weight, height, BMI
C. Fetal ultrasound
D. Fundal height
Correct answer:
The correct answer is B: Weight, height, BMI. During each second-trimester prenatal visit, it is essential to monitor the client's weight, height, and BMI to ensure appropriate maternal and fetal health. Weight gain is a crucial indicator of fetal growth and maternal well-being. Height and BMI can provide insights into the client's nutritional status and overall health.
Explanation of why other choices are incorrect:
A: Cervical examination is typically not performed routinely during second-trimester prenatal visits unless there are specific concerns such as preterm labor risk.
C: Fetal ultrasound is usually scheduled at specific times during pregnancy, not necessarily at every second-trimester visit.
D: Fundal height measurement is important, but it is usually performed starting in the second trimester to assess fetal growth and position, not necessarily at every visit.
The correct answer is D: hormones. The human reproductive system is regulated by hormones such as estrogen, progesterone, testosterone, and others. Hormones play a crucial role in controlling the menstrual cycle, sperm production, ovulation, and other reproductive processes. They help in maintaining the proper functioning of the reproductive organs and influencing sexual characteristics.
A: restriction enzymes are involved in DNA manipulation and have no direct role in regulating the human reproductive system.
B: antigens are substances that trigger an immune response, not involved in regulating the reproductive system.
C: complex carbohydrates are a source of energy and not directly involved in regulating the human reproductive system.
In summary, hormones are the primary regulators of the human reproductive system, influencing various processes essential for reproduction.
A nurse is educating a pregnant patient about warning signs to report during pregnancy. Which of the following statements indicates that the teaching has been effective?
A. I should report any sudden increase in swelling, especially in my hands and face.
B. I should wait until after my due date to report any concerns.
C. I should only report changes in fetal movement after the third trimester.
D. I don't need to report headaches or blurry vision unless they are severe.
Correct answer:
The correct answer is A because sudden increase in swelling, especially in hands and face, can indicate preeclampsia, a serious condition during pregnancy. Swelling in these areas can be a sign of fluid retention and increased blood pressure. Prompt reporting and intervention are crucial to prevent complications for both the mother and the baby.
Choices B, C, and D are incorrect because:
B: Waiting until after the due date to report concerns can lead to missed opportunities for early intervention and can be dangerous for both the mother and the baby.
C: Changes in fetal movement should be reported immediately, not just after the third trimester, as they can indicate fetal distress.
D: Headaches and blurry vision, even if not severe, can be symptoms of preeclampsia or other serious conditions that require immediate attention. Waiting for symptoms to worsen can be harmful.
A patient with newly diagnosed type 1 diabetes is being transitioned from an infusion of intravenous (IV) regular insulin to an intensive insulin therapy regimen of insulin glargine and insulin aspart. How should the nurse manage this transition in insulin delivery?
A. Administer the insulin glargine and continue the IV insulin infusion for 24 hours.
B. Administer the insulin glargine and discontinue the IV infusion in several hours.
C. Discontinue the IV infusion and administer the insulin aspart with the next meal.
D. Discontinue the IV infusion and administer the Lantus insulin at bedtime.
Correct answer:
The correct answer is D: Discontinue the IV infusion and administer the Lantus insulin at bedtime. This is the correct approach because insulin glargine (Lantus) is a long-acting basal insulin that provides a steady level of insulin throughout the day and night. By administering it at bedtime, it mimics the basal insulin secretion in a person without diabetes. This helps maintain stable blood sugar levels overnight.
Choice A is incorrect because continuing the IV insulin infusion for 24 hours alongside insulin glargine is unnecessary and may lead to insulin overdose. Choice B is incorrect because discontinuing the IV infusion in several hours without administering the long-acting insulin can lead to inadequate insulin coverage. Choice C is incorrect because insulin aspart is a rapid-acting insulin that should be given with meals, not as a basal insulin replacement at bedtime.
A muscle that stabilizes the origin of the prime mover so that the prime mover can act more efficiently.
A. superficial
B. synergists
C. fixators
D. aponeurosis
Correct answer:
Fixators are muscles that stabilize the origin of a prime mover, allowing it to move more effectively by preventing unwanted movement at the point of attachment. This stabilization ensures that the force generated by the prime mover is directed toward the intended action, such as lifting or rotating a limb. For example, in shoulder abduction, fixator muscles stabilize the scapula so the deltoid can efficiently lift the arm. Superficial describes muscle location, not function. Synergists assist the prime mover by reducing unnecessary movement or enhancing its action, but they do not specifically stabilize the origin. Aponeurosis is a structural term for a tendon-like sheet, not a muscle type or function. The role of stabilizing the origin is a distinct characteristic of fixators, making it the correct choice here, as it directly supports the prime mover's efficiency in movement.
A nurse is caring for a patient with pneumonia. Which assessment finding would indicate that the treatment is effective?
A. Monitor vital signs for changes.
B. Monitor respiratory status.
C. Monitor oxygen saturation levels.
D. Administer antibiotics as prescribed.
Correct answer:
Step 1: Monitoring vital signs for changes is crucial to assess the patient's overall condition and response to treatment.
Step 2: Vital signs include temperature, pulse rate, respiratory rate, and blood pressure.
Step 3: Improvement in vital signs such as decreased temperature, heart rate, and respiratory rate would indicate treatment effectiveness.
Step 4: Respiratory status and oxygen saturation levels are important but may not provide a comprehensive assessment of treatment efficacy.
Step 5: Administering antibiotics is part of the treatment plan but does not directly indicate treatment effectiveness.
Summary: Monitoring vital signs for changes is the most direct and reliable way to assess the effectiveness of treatment for pneumonia, making it the correct choice. The other options may provide valuable information but are not as direct indicators of treatment efficacy.
The nurse is providing prenatal education to a pregnant patient at 24 weeks gestation. Which of the following topics should the nurse prioritize during this visit?
A. Signs and symptoms of preterm labor and when to call the healthcare provider
B. Breastfeeding techniques and infant care
C. Postpartum care and family planning options
D. Managing pregnancy-related fatigue and morning sickness
Correct answer:
The correct answer is A: Signs and symptoms of preterm labor and when to call the healthcare provider. This is the most crucial topic to prioritize at 24 weeks gestation because preterm labor can have serious consequences for both the mother and the baby. By educating the patient on the signs and symptoms of preterm labor, such as abdominal cramping, backache, or vaginal bleeding, the nurse can empower the patient to recognize these warning signs early and seek prompt medical attention, potentially preventing preterm birth.
Choice B: Breastfeeding techniques and infant care, and Choice C: Postpartum care and family planning options are important topics but are more relevant for later stages of pregnancy or after delivery. Choice D: Managing pregnancy-related fatigue and morning sickness is also important but is generally not as urgent as being aware of signs of preterm labor.
While administering normal saline to an adult patient experiencing hypovolemia, the medical command physician recommends the administration of warm normal saline, even though it is not a cold environment. Why would a physician (MCP) recommend warmed normal saline be administered to an adult hypovolemia patient?
A. Warm saline has a better affinity to oxygen transport to the cells
B. To help maintain a normal body temperature during hypovolemia
C. Warm saline will require less energy to enter the systemic circulation
D. It will increase the amount of cardiac output more rapidly
Correct answer:
The correct answer is B: To help maintain a normal body temperature during hypovolemia.
Rationale:
1. When a patient is experiencing hypovolemia, their body is already under stress, potentially leading to a decrease in body temperature.
2. Administering warm normal saline helps prevent further cooling of the body and aids in maintaining a normal body temperature.
3. Maintaining normal body temperature is crucial for proper physiological functions and overall patient well-being during hypovolemia.
Summary of other choices:
A: Warm saline's temperature does not affect its affinity for oxygen transport.
C: The energy required for warm saline to enter circulation is not significantly different from room temperature saline.
D: Warm saline may slightly affect cardiac output due to temperature, but the primary reason for warming saline is to maintain body temperature in hypovolemia.
During the examination of a patient, who had been to the mountain pasture and had been hospitalized in a bad condition with fever, the doctor found out the enlargement of inguinal lymph nodes to 8 cm, which were attached to the surrounding tissues, immovable, the skin above them was red and tender. The microscopic examination of the node revealed acute serohemorrhagic inflammation. What disease is it typical for?
A. Brucellosis
B. Plague
C. Anthrax
D. Tularemia
Correct answer:
Rationale:
1. The patient has symptoms of fever, enlarged lymph nodes, red and tender skin, which are indicative of systemic infection.
2. The inguinal lymph nodes in plague become enlarged, tender, and painful, forming buboes.
3. The presence of acute serohemorrhagic inflammation in the lymph node is characteristic of plague.
4. Plague is a zoonotic bacterial infection caused by Yersinia pestis, commonly transmitted through fleas from rodents.
5. Brucellosis, anthrax, and tularemia do not typically present with inguinal lymph node involvement and acute serohemorrhagic inflammation.
Summary:
- Brucellosis: Usually presents with flu-like symptoms, joint pain, and fever, not inguinal lymph node enlargement.
- Anthrax: Presents with skin lesions, respiratory symptoms, or gastrointestinal symptoms, not inguinal lymph node involvement.
- Tularemia: Presents with fever, skin ulcers,
A nurse is evaluating a nursing assistive personnel’s(NAP) care for a patient with an indwelling catheter. Which action by the NAP will cause the nurse to intervene?
A. Emptying the drainage bag when half full
B. Kinking the catheter tubing to obtain a urine specimen
C. Placing the drainage bag on the side rail of the patient’s bed
D. Securing the catheter tubing to the patient’s thigh
Correct answer:
Placing the drainage bag on the side rail of the bed could allow the bag to be raised above the level of the bladder and urine to flow back into the bladder. The urine in the drainage bag is a medium for bacteria; allowing it to reenter the bladder can cause infection. A key intervention to prevent catheter-associated urinary tract infections is prevention of urine back flow from the tubing and bag into the bladder. All the other actions are correct procedures and do not require immediate follow-up. The drainage bag should be emptied when it is half full to prevent tension and pulling on the catheter, which could result in trauma to the urethra and increase the risk for urinary tract infections. Urine specimens are traditionally obtained by temporarily kinking the tubing, while securing the catheter tubing to the patient’s thigh prevents catheter dislodgment and tissue injury.
