Five pharmacology questions with answers
Cover the key. Write the first action. Then open the rationale and name why the other choices fail.
Question 1
What is the primary purpose of using measurable client outcomes during the nursing process?
A. To diagnose client conditions accurately.
B. To evaluate the effectiveness of nursing interventions.
C. To prioritize nursing diagnoses effectively.
D. To guide documentation in the client’s health record.
Show answer and rationale
Correct answer: B — To evaluate the effectiveness of nursing interventions.
The primary purpose of using measurable client outcomes during the nursing process is to evaluate the effectiveness of nursing interventions. This is crucial in determining whether the care provided has led to the desired outcomes for the client's health. By measuring outcomes, nurses can assess if the interventions are successful, make any necessary adjustments to the care plan, and ensure optimal patient outcomes.
Choice A is incorrect because diagnosing client conditions accurately is not the primary purpose of using measurable client outcomes; it is more related to the initial assessment phase.
Choice C is incorrect because prioritizing nursing diagnoses effectively is an important aspect of the nursing process, but it is not the primary purpose of using measurable client outcomes.
Choice D is incorrect because while documentation in the client's health record is important, it is not the primary purpose of using measurable client outcomes.
Question 2
The nurse is conducting a nursing history of a client with a respiratory rate of 30, audible wheezing, and nasal flaring. During the interview, the client denies problems with breathing. What action should the nurse take next?
A. Clarify discrepancies of assessment data with the client.
B. Validate client data with members of the health care team.
C. Document all data collected in the nursing history and physical examination.
D. Seek input from family members regarding the client’s breathing at home.
Show answer and rationale
Correct answer: A — Clarify discrepancies of assessment data with the client.
Step-by-step rationale:
1. The nurse should clarify discrepancies of assessment data with the client to ensure accurate information.
2. The client's denial of breathing problems conflicts with physical signs, indicating a potential lack of awareness or reluctance to disclose symptoms.
3. By clarifying with the client, the nurse can address any misunderstandings or encourage honest communication.
4. This approach promotes client-centered care and ensures a comprehensive understanding of the client's health status.
Summary:
- Choice A is correct as it addresses the need to clarify discrepancies with the client for accurate assessment.
- Choice B is incorrect as validation with the healthcare team may not provide insight into the client's perception.
- Choice C is incorrect as it does not address the need to resolve conflicting assessment data.
- Choice D is incorrect as family input may not provide accurate information if the client denies symptoms.
Question 3
Which of the following drugs is an insulin secretagogue:
A. Metformin
B. Pioglitazone
C. Repaglinide
D. Hydrochlorothiazide
Show answer and rationale
Correct answer: C — Repaglinide
Insulin secretagogues stimulate pancreatic beta cells to release insulin. Repaglinide (choice C), a meglitinide, does this by closing ATP-sensitive potassium channels, depolarizing beta cells, and triggering insulin secretion, useful in type 2 diabetes for postprandial glucose control. Metformin (choice A), a biguanide, reduces hepatic glucose production and improves insulin sensitivity, not secretion. Pioglitazone (choice B), a thiazolidinedione, enhances insulin sensitivity in peripheral tissues, not directly stimulating insulin release. Hydrochlorothiazide (choice D), a diuretic, affects blood pressure and electrolytes, unrelated to insulin secretion. Repaglinide's mechanism aligns with the secretagogue definition, distinguishing it from other antidiabetic classes. This understanding is crucial for tailoring therapy to patient needs, especially in managing hyperglycemia effectively while avoiding hypoglycemia risks associated with secretagogues.
Question 4
Fluoroquinolone antibiotics are most likely indicated in which of the following conditions?
A. Asthma
B. Follicular conjunctivitis
C. GERD
D. Genital infections
Show answer and rationale
Correct answer: D — Genital infections
The correct answer is D: Genital infections. Fluoroquinolone antibiotics are commonly used to treat bacterial infections in the genital area due to their broad spectrum of activity against various types of bacteria commonly implicated in these infections. They are effective against pathogens such as Chlamydia, Gonorrhea, and other sexually transmitted infections.
A: Asthma - Fluoroquinolones are not indicated for the treatment of asthma as they are not effective against the underlying causes of asthma such as inflammation and bronchoconstriction.
B: Follicular conjunctivitis - While fluoroquinolones can be used topically in the eye for certain eye infections, they are not typically indicated for follicular conjunctivitis which often requires different types of antibiotics.
C: GERD - Fluoroquinolones are not used to treat GERD (Gastroesophageal Reflux Disease) which is a condition related to stomach acid reflux into the esophagus. Antacids
Question 5
Which of the following drugs is an insulin secretagogue:
A. Metformin
B. Pioglitazone
C. Repaglinide
D. Hydrochlorothiazide
Show answer and rationale
Correct answer: C — Repaglinide
Insulin secretagogues stimulate pancreatic beta cells to release insulin. Repaglinide (choice C), a meglitinide, does this by closing ATP-sensitive potassium channels, depolarizing beta cells, and triggering insulin secretion, useful in type 2 diabetes for postprandial glucose control. Metformin (choice A), a biguanide, reduces hepatic glucose production and improves insulin sensitivity, not secretion. Pioglitazone (choice B), a thiazolidinedione, enhances insulin sensitivity in peripheral tissues, not directly stimulating insulin release. Hydrochlorothiazide (choice D), a diuretic, affects blood pressure and electrolytes, unrelated to insulin secretion. Repaglinide's mechanism aligns with the secretagogue definition, distinguishing it from other antidiabetic classes. This understanding is crucial for tailoring therapy to patient needs, especially in managing hyperglycemia effectively while avoiding hypoglycemia risks associated with secretagogues.

A 45-year-old woman has just received a kidney transplant. She is placed on several immunosuppressants to prophylactically prevent her body rejecting the donor organ. Which of the following immunosuppressants interferes with T-cell activation by modifying the activity of calcineurin?
A. Cyclosporine
B. Methotrexate
C. Prednisolone
D. Sirolimus
Correct answer:
Post-kidney transplant, immunosuppression prevents rejection by targeting T-cell activation. Cyclosporine binds calcineurin, inhibiting its phosphatase activity, which blocks IL-2 transcription, crucial for T-cell proliferation-making it the correct answer. Methotrexate inhibits purine synthesis, affecting rapidly dividing cells, not calcineurin. Prednisolone , a corticosteroid, suppresses inflammation broadly but doesn't target calcineurin. Sirolimus inhibits mTOR, a different pathway, affecting T-cell proliferation downstream, not calcineurin. Temsirolimus (E) is similar to sirolimus. Cyclosporine's specificity to calcineurin aligns with the question's focus, a cornerstone in transplant regimens. Its mechanism disrupts early T-cell signaling, critical for alloimmune responses, unlike the broader or alternative actions of other options. This precision ensures effective prophylaxis while distinguishing it from other immunosuppressants in the list.
The female client has a fungal infection and will receive nystatin (Mycostatin). What assessment data is critical for the nurse to review prior to administering this medication?
A. The type of diet the client is eating
B. The amount of fat in the client's diet
C. Whether the patient could be pregnant
D. The client's height and weight
Correct answer:
Nystatin is an antifungal medication used to treat fungal infections, such as candidiasis. Before administration, assessing whether the client could be pregnant is critical because nystatin's safety in pregnancy is not fully established (Category C), meaning potential risks to the fetus cannot be ruled out without further evaluation. This makes pregnancy status a key safety consideration to prevent harm to an unborn child, outweighing other factors in urgency. The type of diet or amount of fat might influence general health or drug absorption minimally but isn't directly critical to nystatin's administration. Height and weight could affect dosing in some medications, but nystatin's dosing is typically standard and not weight-based for most fungal infections. Thus, confirming pregnancy status ensures the drug's safety profile aligns with the client's condition, making choice C the most critical assessment data to review prior to administration.
The data shown in the table below concern the effects of drugs on transmitter function in the CNS. Which one of the drugs is most likely to alleviate extrapyramidal dysfunction caused by typical antipsychotics?
A. DA receptor activation
B. DA, GABA activation
C. 0 DA, 0 GABA, ACh M receptor block
D. 0 DA, GABA activation
Correct answer:
Typical antipsychotics block dopamine D2 receptors, causing extrapyramidal symptoms (EPS) like parkinsonism due to dopamine-acetylcholine imbalance in the basal ganglia. Drugs alleviating EPS often restore this balance. Drug A strongly activates dopamine receptors, mimicking dopamine and potentially countering the blockade, but excessive activation risks psychosis. Drug B moderately boosts dopamine and GABA, offering some benefit but less specificity. Drug C potently blocks muscarinic acetylcholine receptors, reducing cholinergic overactivity that emerges from dopamine depletion, a well-established approach (e.g., benztropine) for EPS relief without worsening psychosis. Drug D enhances GABA, unrelated to EPS mechanisms. Drug E mildly activates dopamine and GABA, insufficient for robust relief. Blocking muscarinic receptors directly addresses the cholinergic excess, making it the most effective and clinically validated strategy for EPS management.
A 6-year-old boy presents to his pediatrician for followup of recurrent hay fever and asthma. He usually has two to three attacks per week. For symptom control, he uses an albuterol inhaler, but his parents would like to try something more. They would like him to take something that would lessen the amount of attacks he has. Although corticosteroids would probably work best for prophylaxis, they are contraindicated in children. Which of the following drugs would decrease the amount of asthma attacks by preventing an arachidonic acid derivative from binding to its receptor?
A. Aspirin
B. Celecoxib
C. Ipratropium
D. Montelukast
Correct answer:
Asthma attacks in this case are driven by inflammation, often mediated by leukotrienes, which are arachidonic acid derivatives. The goal is to reduce the frequency of attacks by targeting this pathway. Aspirin inhibits cyclooxygenase (COX), reducing prostaglandins but not leukotrienes, and may even worsen asthma in some patients. Celecoxib is a selective COX-2 inhibitor, also irrelevant to leukotrienes. Ipratropium is an anticholinergic bronchodilator, effective for acute symptom relief but not prophylaxis via arachidonic acid pathways. Montelukast is a leukotriene receptor antagonist, directly preventing leukotrienes from binding to their receptors, thus reducing inflammation and attack frequency. Zileuton (E), while a leukotriene synthesis inhibitor, isn't the best choice here as the question specifies receptor binding prevention, not synthesis inhibition. Montelukast aligns perfectly with the mechanism described, making it the correct answer.
The nurse is assigned to care for a postoperative client who has diabetes mellitus. During the assessment interview, the client reports that he’s impotent and says he’s concerned about its effect on his marriage. In planning this client’s care, the most appropriate intervention would be to:
A. Encourage the client to ask questions about personality sexuality
B. Provide time for privacy
C. Provide support for the spouse or significant other
D. Suggest referral to a sex counselor or other appropriate professional
Correct answer:
The correct answer is D: Suggest referral to a sex counselor or other appropriate professional. This is the most appropriate intervention as it addresses the client's concern about impotence affecting his marriage by offering specialized help from a professional who can provide counseling and guidance on managing sexual issues related to diabetes. Referring the client to a sex counselor ensures that he receives expert support in addressing his specific concerns and helps improve his overall well-being and quality of life.
A: Encouraging the client to ask questions about personality sexuality may not address the underlying issue of impotence and its impact on the marriage.
B: Providing time for privacy is important but may not directly address the client's concerns about impotence.
C: Providing support for the spouse or significant other is beneficial, but the primary focus should be on addressing the client's specific concerns about impotence.
The client has MRSA and receives vancomycin (Vancocin) intravenously (IV). The nurse assesses an upper body rash and decreased urine output. What is the nurse's priority action?
A. Hold the next dose of vancomycin (Vancocin) and notify the physician.
B. Obtain a stat X-ray and notify the physician.
C. Administer an antihistamine and notify the physician.
D. Obtain a sterile urine specimen and notify the physician.
Correct answer:
Vancomycin is an antibiotic used to treat serious infections like MRSA, but it can cause significant adverse effects, including nephrotoxicity (kidney damage) and hypersensitivity reactions, such as rashes. The symptoms of an upper body rash and decreased urine output suggest a possible allergic reaction or renal impairment, both of which are potentially life-threatening if the drug continues to be administered. Holding the next dose prevents further exposure to the drug, which could exacerbate the reaction or damage, while notifying the physician ensures prompt medical evaluation and intervention. Obtaining an X-ray or urine specimen might provide additional data but doesn't address the immediate risk. Administering an antihistamine could mask symptoms without addressing the underlying issue, potentially delaying critical treatment. Thus, the priority is to stop the drug and seek physician guidance, making choice A the most appropriate action.
Which of the following drugs acts as a competitive benzodiazepine receptor antagonist:
A. Naloxone
B. Flumazenil
C. Flurazepam
D. Disulfuram
Correct answer:
A competitive benzodiazepine receptor antagonist binds to the GABAa receptor's benzodiazepine site, preventing agonists like diazepam from exerting effects, without activating the receptor itself. Flumazenil is this antagonist, used to reverse benzodiazepine overdose (e.g., reversing sedation or respiratory depression) by competitively displacing agonists. Naloxone (choice A) is an opioid antagonist, targeting mu receptors to reverse opioid overdose, not benzodiazepine-related. Flurazepam (choice C) is a benzodiazepine agonist, promoting GABA effects, not blocking them. Disulfuram (choice D, likely misspelled) inhibits aldehyde dehydrogenase for alcoholism treatment, unrelated to benzodiazepine receptors. Flumazenil's specificity and competitive nature make it the correct choice. This question emphasizes antidote recognition, critical in emergency settings to counteract CNS depression, distinguishing it from other reversal agents like Naloxone.
