A nurse is caring for a patient with chronic kidney disease (CKD). Which of the following lab results would the nurse expect to be elevated in this patient?

Correct Answer: A

Rationale: The correct answer is A: Blood urea nitrogen (BUN). In CKD, the kidneys are unable to effectively filter waste products, leading to an increase in BUN levels. Elevated BUN indicates impaired kidney function. Calcium, potassium, and sodium levels may also be affected in CKD, but they are more likely to be imbalanced rather than consistently elevated. Calcium levels may be low due to impaired vitamin D activation, potassium levels may be high due to decreased excretion, and sodium levels can fluctuate based on fluid status. Therefore, while these lab values may be abnormal in CKD, BUN is the most consistently elevated marker of kidney dysfunction.

Correct Answer: D

Rationale: The correct answer is D because it indicates a potential concern about the girl's mental health. This behavior may suggest a difficulty in socializing with peers of her own age, which could be a sign of emotional distress or developmental issues. This is concerning in the context of her parents' bitter divorce. A: Clinging to her mother is a common behavior for a child going through a stressful situation, so it may not necessarily indicate a mental health issue. B: Appearing angry and avoiding eye contact could also be a normal reaction to stress or discomfort. C: Riding a tricycle is a typical activity for a 5-year-old and may not directly relate to mental health concerns.

Correct Answer: D

Rationale: The correct answer is D. Hypertension can lead to various complications affecting the heart, kidneys, and brain. Monitoring for heart failure is crucial due to the increased workload on the heart. Chronic kidney disease is a common complication of hypertension, as the kidneys are sensitive to changes in blood pressure. Stroke is another significant risk due to the potential damage to blood vessels in the brain. Therefore, monitoring for all these complications is essential in managing a patient with hypertension. Other choices are incorrect as they do not encompass all possible complications of hypertension.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. This is the first step in the care of a client with a severe allergic reaction because epinephrine is the primary medication used to reverse the life-threatening symptoms of anaphylaxis. Epinephrine acts quickly to constrict blood vessels, relax smooth muscles in the lungs to improve breathing, and increase heart rate. Administering epinephrine promptly can prevent progression to severe outcomes like respiratory failure or shock. Corticosteroids (B and C) are used as adjunct therapy and do not provide immediate relief. Applying a cold compress (D) does not address the systemic effects of anaphylaxis and can delay potentially life-saving treatment.

Correct Answer: A

Rationale: Step 1: Lisinopril is an ACE inhibitor commonly prescribed post-myocardial infarction to reduce strain on the heart and prevent further damage. Step 2: ACE inhibitors like Lisinopril help lower blood pressure and improve heart function. Step 3: By reducing the workload on the heart, Lisinopril can help prevent complications post-MI. Step 4: Acetaminophen (B) is a pain reliever and does not address the cardiovascular issues post-MI. Step 5: Furosemide (C) and Hydrochlorothiazide (D) are diuretics typically used for managing fluid retention, not the primary focus after an MI. Summary: Lisinopril is the correct choice as it helps improve heart function and prevent complications post-MI, unlike the other options which do not directly address the cardiovascular issues associated with MI.

Correct Answer: A

Rationale: Rationale: 1. Collecting a follow-up database ensures up-to-date information. 2. It allows for monitoring of medication effectiveness and any new symptoms. 3. Checking the blood pressure is essential but needs current context. 4. Asking the patient to read her record may not provide all necessary updates. 5. The complete health history is crucial but obtaining it first may delay urgent blood pressure check.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. In acute renal failure, the priority is to maintain adequate hydration to support kidney function. IV fluids help improve renal perfusion and urine output. Monitoring vital signs is important but not the priority. Performing a kidney function test can provide valuable information but does not address the immediate need for fluid resuscitation. Administering IV antibiotics may be necessary if there is an infection contributing to renal failure, but hydration takes precedence. In summary, administering IV fluids is crucial to support kidney function in acute renal failure, making it the top priority among the choices given.

Correct Answer: A

Rationale: The correct first action is A: Apply pressure and elevate the limb. This is because applying pressure helps control bleeding and elevating the limb reduces blood flow to the area, minimizing further blood loss. This immediate intervention is crucial in managing the traumatic amputation and preventing complications. Summary of why other choices are incorrect: B: Stopping bleeding and controlling shock can be important but not the first action. C: Placing the client in a Trendelenburg position (feet elevated higher than the head) is contraindicated in cases of traumatic amputation as it can increase bleeding. D: Placing the client in a sitting position is not appropriate as it can worsen bleeding and lead to further complications.

Correct Answer: B

Rationale: Acyclovir is a nucleoside analog antiviral drug that is specifically effective against herpes simplex virus (HSV) types 1 and 2, as well as varicella-zoster virus (VZV). The drug works by inhibiting viral DNA synthesis. HSV and VZV are both members of the herpes virus family, and acyclovir is most commonly prescribed for infections caused by these viruses. Therefore, the correct answer is B. Choice A (HIV) is incorrect because acyclovir is not effective against HIV. Choice C (CMV) is incorrect because acyclovir is less effective against cytomegalovirus (CMV) compared to HSV and VZV. Choice D (influenza A viruses) is incorrect because acyclovir is not indicated for the treatment of influenza viruses.
