1. In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.

2. 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.

3. The nurse is caring for a client with cirrhosis of the liver and suspects that the client may be developing hepatic encephalopathy. Which assessment by the nurse suggests that the client is developing this complication?

• A. Asterixis
• B. Hypertension
• C. Kussmaul respirations
• D. Lethargy

Correct answer: A

Rationale: Asterixis, also known as flapping tremors, is a characteristic sign of hepatic encephalopathy. It is a flapping tremor of the hands when the wrists are extended, indicating neurological impairment. Hypertension and Kussmaul respirations are not directly associated with hepatic encephalopathy. Lethargy is a common symptom but not a specific sign that suggests the development of hepatic encephalopathy.

4. A client is admitted to telemetry with a diagnosis of diabetes at 3pm. At 10pm, the client is unresponsive. BP is 98/64, Resp 38, HR 100, T 97. The nurse notes a fruity smell on the client's breath. The nurse recognizes that the client is in which acid-base imbalance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: C

Rationale: Based on the client's unresponsiveness, fruity breath smell, and the presence of diabetes, the nurse can infer that the client is experiencing diabetic ketoacidosis (DKA). DKA is a complication of diabetes characterized by the accumulation of ketones in the body, leading to metabolic acidosis. The fruity breath smell is due to the presence of ketones. Therefore, the correct acid-base imbalance in this scenario is metabolic acidosis. Choice A, respiratory acidosis, is incorrect because the scenario does not provide evidence of primary respiratory dysfunction. Choice B, respiratory alkalosis, is incorrect as the client's condition does not align with the typical causes and symptoms of respiratory alkalosis. Choice D, metabolic alkalosis, is incorrect as the symptoms and history provided do not suggest a state of metabolic alkalosis.

5. The nurse teaching about preventable diseases should emphasize the importance of getting the following vaccines:

• A. human papillomavirus, genital herpes, measles.
• B. pneumonia, HIV, mumps.
• C. syphilis, gonorrhea, pneumonia.
• D. polio, pertussis, measles.

Correct answer: D

Rationale: Vaccines are one of the most effective methods of preventing and controlling certain communicable diseases. The smallpox vaccine is not currently in use because the smallpox virus has been declared eradicated from the world's population. Diseases such as polio, diphtheria, pertussis, and measles are mostly controlled by routine childhood immunization. They have not, however, been eradicated, so children need to be immunized against these diseases. Choices A, B, and C contain vaccines that do not protect against preventable diseases like polio, pertussis, and measles. Therefore, the correct choice is D.
