Nursing Elites

1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

2. A nurse is assessing an 18-year-old female who has recently suffered a TBI. The nurse notes a slower pulse and impaired respiration. The nurse should report these findings immediately to the physician due to the possibility the patient is experiencing which of the following conditions?

• A. Increased intracranial pressure
• B. Increased function of cranial nerve X
• C. Sympathetic response to activity
• D. Meningitis

Correct answer: A

Rationale: The nurse should report the slower pulse and impaired respiration to the physician immediately as they are indicative of increased intracranial pressure (ICP) following a traumatic brain injury (TBI). These signs suggest that there may be a rise in pressure within the skull, which can be a life-threatening condition requiring urgent intervention. Options B and C are unlikely in this scenario as they do not correlate with the symptoms presented. Meningitis (Option D) typically presents with different signs and symptoms, such as fever, headache, and neck stiffness, which are not described in the patient's case.

3. A nurse assesses an 83-year-old female's venous ulcer for the second time that is located near the right medial malleolus. The wound is exhibiting purulent drainage, and the patient has limited mobility in her home. Which of the following is the best course of action?

• A. Encourage warm water soaks to the right foot.
• B. Notify the case manager of the purulent drainage.
• C. Determine the patient's pulse in the right ankle.
• D. Recommend increased activity to reduce the purulent drainage.

Correct answer: A

Rationale: The correct course of action is to encourage warm water soaks to the right foot. This can help promote wound healing and alleviate discomfort. Before recommending increased activity or notifying additional team members, it is crucial to assess arterial blood flow by determining the patient's pulse in the right ankle. Poor arterial blood flow could worsen the condition, making increased activity inappropriate. While notifying the case manager of purulent drainage is important, addressing the wound care directly should be the primary focus at this stage.

4. A client admitted with an episode of bleeding esophageal varices is receiving propranolol (Inderal LA). The nurse knows to monitor for?

• A. Hypertension
• B. Hyperkalemia
• C. Bradycardia
• D. Arthralgia

Correct answer: C

Rationale: The correct answer is 'Bradycardia.' Propranolol is a beta-blocking agent used to decrease the heart rate. In the case of bleeding esophageal varices, propranolol is given to reduce the risk of bleeding by keeping the heart rate around 55 beats per minute. Monitoring for bradycardia is essential as the medication's intended effect is to lower the heart rate. Choices A, B, and D are incorrect because propranolol would not typically cause hypertension, hyperkalemia, or arthralgia.

5. What is the drug of choice for herpes simplex virus 1, herpes simplex virus 2, and varicella-zoster virus?

• A. HIV.
• B. HSV 1, HSV 2, and VZV.
• C. CMV
• D. Influenza A viruses.

Correct answer: B

Rationale: Acyclovir (Zovirax) is the drug of choice for herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), and varicella-zoster virus (VZV) infections. It works by inhibiting viral DNA replication. Acyclovir is excreted unchanged in the urine, so caution is needed in renal impairment. Choice A, HIV, is incorrect as acyclovir is not the drug of choice for HIV. Choice C, CMV, is incorrect as acyclovir is not the preferred treatment for cytomegalovirus (CMV) infections. Choice D, Influenza A viruses, is incorrect as acyclovir is not used to treat influenza viruses.
