RN exams clinical judgment practice questions set 27

Correct answer:

Correct Answer: C - Administering an enema Rationale: Administering an enema is a task that can be safely delegated to nursing assistive personnel (NAP) as it is within their scope of practice and does not require the specialized knowledge and skills of a registered nurse. NAP can be trained to perform enema administration safely and effectively, under the supervision of a nurse. This task involves following a specific procedure and does not require clinical judgment or decision-making. Summary of other choices: A: Performing the first postoperative pouch change - This task involves wound care and assessment, which require the expertise of a registered nurse. B: Maintaining a nasogastric tube - This task involves ongoing assessment, monitoring for complications, and adjustments, which are responsibilities of a registered nurse. D: Digitally removing stool - This task involves invasive procedures and assessment, which are beyond the scope of practice for nursing assistive personnel.

Correct answer:

The correct answer is B: Most women avoid cesarean births unless it is an emergency. Rationale: 1. Cesarean delivery is a major surgery with potential risks and longer recovery time compared to vaginal birth. 2. Most women opt for vaginal birth unless there are medical reasons necessitating a cesarean section. 3. It is important for the nurse to educate the patient on the benefits of vaginal birth and address her fears about the birth experience. 4. Encouraging the patient to consider vaginal birth unless there is a medical emergency aligns with best practices in obstetric care. Summary: - Choice A is incorrect because focusing solely on pain management may not address the patient's underlying fear of the birth experience. - Choice C is incorrect as seeking another opinion may not be necessary if the patient's concerns can be addressed through education and counseling. - Choice D is incorrect as not all cesarean deliveries lead to complications in subsequent pregnancies.

Correct answer:

Benzodiazepines (e.g., diazepam, lorazepam) are CNS depressants used for anxiety, seizures, and insomnia. They exert effects by binding to a specific allosteric site on the GABAa receptor, enhancing GABA's inhibitory action. GABA, the primary inhibitory neurotransmitter, opens chloride (Cl⁻) channels, hyperpolarizing neurons and reducing excitability. Benzodiazepines increase the frequency of channel opening, potentiating this effect, leading to sedation and anxiolysis. Blocking Cl⁻ channels (choice A) would oppose inhibition, contrary to their purpose. Acting as direct agonists (choice C) is incorrect—they don't activate the receptor alone but amplify GABA's action. Antagonizing GABAb receptors (choice D) is irrelevant, as benzodiazepines target GABAa specifically. This potentiation mechanism underlies their therapeutic utility and risks like tolerance. Understanding this is key to distinguishing benzodiazepines from other CNS drugs and managing their clinical use effectively.

Correct answer:

Muscle structure follows a hierarchy from largest to smallest: the whole muscle (e.g., biceps), encased by epimysium, contains fascicles bundles of fibers wrapped in perimysium. Each fascicle holds muscle fibers, single elongated cells in endomysium, visible under light microscopy. Within fibers, myofibrils, rod-like organelles, house sarcomeres, the contractile units. This sequence muscle (centimeters), fascicle (millimeters), fiber (micrometers), myofibril (nanometers) reflects anatomical nesting. Reversing fascicle and fiber misaligns bundles with cells, while placing myofibrils before fibers ignores their intracellular role. A whole muscle, spanning bone to bone, dwarfs fascicles (10-100 fibers), which outsize fibers (10-100 micrometers wide), containing hundreds of myofibrils. Dissection and electron microscopy confirm this descending scale, critical for understanding force transmission from sarcomeres to gross movement, distinguishing organizational levels in muscle physiology.

Correct answer:

The correct action to take first is to assess the patient's blood pressure and check for signs of preeclampsia (Answer A). Preeclampsia is a serious condition characterized by high blood pressure and signs of organ dysfunction. In this scenario, the patient's severe swelling could be indicative of preeclampsia, which poses a risk to both the mother and the fetus. By assessing blood pressure and looking for other signs of preeclampsia, the nurse can determine the urgency of the situation and take appropriate actions to manage the condition. Encouraging leg elevation and rest (Answer B) may help alleviate some symptoms but does not address the underlying cause of the swelling. Monitoring urine output (Answer C) is important for overall assessment but does not address the immediate concern of potential preeclampsia. Scheduling an ultrasound (Answer D) is not the priority in this situation as it does not provide information about the patient's current condition and does not address the

Correct answer:

The primary purpose of an abdominal binder after surgery is to increase circulation. An abdominal binder helps improve blood flow to the surgical site, which can aid in reducing swelling, promoting healing, and preventing complications such as blood clots. It provides gentle compression to support the abdominal muscles and tissues without restricting circulation. Choice A (Promote comfort) is incorrect because while an abdominal binder may provide some comfort by supporting the abdomen, its primary purpose is not solely for comfort. Choice B (Prevent infection) is incorrect because an abdominal binder does not directly prevent infection. Infection prevention is primarily achieved through proper wound care and infection control practices. Choice D (Provide wound care) is incorrect because an abdominal binder does not provide wound care. Wound care involves cleaning, dressing changes, and monitoring for signs of infection, which are separate from the purpose of an abdominal binder.

Correct answer:

The correct answer is C: Procedures performed in the operating room are associated with fewer complications. This is because performing a tracheostomy in the operating room allows for better control of the environment, equipment, and expertise of the surgical team. In this setting, the risk of complications such as bleeding, infection, and injury to surrounding structures is minimized. Choices A, B, and D are incorrect: A: Patient outcomes are better if the tracheostomy is done within a week of intubation - This statement is not universally true and depends on individual patient factors. Timing of tracheostomy should be based on the patient's clinical condition and not a set timeline. B: Percutaneous tracheostomy can be done safely at the bedside by the respiratory therapist - While percutaneous tracheostomy can be performed at the bedside, it is typically done by a trained physician or surgeon due to the potential risks and complications involved. D: The greatest risk after a per

Correct answer:

The correct answer is D: Determine the patient’s work of breathing. Assessing the exhaled tidal volume (EV) in a mechanically ventilated patient helps determine how much effort the patient is exerting to breathe. By monitoring the EV, the nurse can evaluate the patient's respiratory status and adjust ventilator settings if needed. It is crucial to ensure that the patient is not working too hard to breathe, as this can lead to respiratory distress. Incorrect answers: A: Assess for tension pneumothorax - Tension pneumothorax is typically assessed through other means such as physical examination and chest X-ray. B: Assess the level of positive end-expiratory pressure - The level of positive end-expiratory pressure is usually set based on the patient's condition and not solely based on the exhaled tidal volume. C: Compare the tidal volume delivered with the tidal volume prescribed - This comparison is important but does not directly relate to assessing the patient's work of breathing.

Correct answer:

Answer A is correct because active listening involves using nonverbal cues such as leaning forward, focusing on the speaker's face, and nodding slightly to show that you are engaged and understanding the message. Leaning forward demonstrates interest, focusing on the face shows attentiveness, and nodding indicates acknowledgment. These actions encourage the speaker to continue sharing and feel heard. Choices B, C, and D are incorrect: B: Avoiding eye contact can make the speaker feel ignored or disconnected, which goes against the principles of active listening. C: Anticipating what the speaker is trying to say and finishing their sentences is not active listening; it can be seen as interrupting and not allowing the speaker to express themselves fully. D: Asking probing questions and directing the conversation towards obtaining specific information efficiently is not active listening. It can come across as controlling the conversation rather than actively listening to the speaker.
