Nursing Elites

1. A client has a long history of hypertension. Which category of medication would the nurse expect to be ordered to avoid chronic kidney disease (CKD)?

• A. Antibiotic
• B. Histamine blocker
• C. Bronchodilator
• D. Angiotensin-converting enzyme (ACE) inhibitor

Correct answer: D

Rationale: The correct answer is D, Angiotensin-converting enzyme (ACE) inhibitor. ACE inhibitors inhibit the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By blocking this conversion, ACE inhibitors promote vasodilation and improve perfusion to the kidneys. Additionally, ACE inhibitors block the breakdown of bradykinin and prostaglandin, further contributing to vasodilation. They also lead to increased renin and decreased aldosterone levels. These effects help in reducing blood pressure and protecting the kidneys in clients with hypertension. Antibiotics are used to fight infections, histamine blockers reduce inflammation, and bronchodilators widen the bronchi, none of which address the underlying processes involved in slowing the progression of chronic kidney disease (CKD) in hypertensive clients.

2. A female patient who is allergic to penicillin will begin taking an antibiotic to treat a lower respiratory tract infection. The patient tells the nurse that she almost always develops a vaginal yeast infection when she takes antibiotics and that she will take fluconazole (Diflucan) with the antibiotic being prescribed. Which macrolide should the nurse question for this patient?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Erythromycin (E-Mycin)
• D. Fidaxomicin (Dificid)

Correct answer: C

Rationale: The nurse should question the prescription of erythromycin for this patient. When erythromycin is given concurrently with fluconazole, erythromycin blood concentration and the risk of sudden cardiac death increase. Therefore, it is not recommended to use erythromycin in combination with fluconazole for this patient. Azithromycin, clarithromycin, and fidaxomicin are alternative macrolide antibiotics that can be considered for this patient without the same risk of interactions when used with fluconazole.

3. The client with chronic renal failure is being taught about the importance of fluid restrictions. Which of the following statements by the client indicates that the teaching has been effective?

• A. I can drink as much fluid as I want, as long as I take my medication.
• B. I will need to limit my fluid intake to prevent fluid overload.
• C. I can drink as much water as I want, as long as I limit other fluids.
• D. I will need to drink only when I am thirsty.

Correct answer: B

Rationale: The correct answer is B: 'I will need to limit my fluid intake to prevent fluid overload.' In chronic renal failure, fluid restrictions are crucial to prevent fluid overload and further damage to the kidneys. Option A is incorrect as unrestricted fluid intake can worsen the condition. Option C is also incorrect as total fluid intake needs to be restricted, not just other fluids. Option D is not ideal because thirst may not accurately reflect the body's fluid needs in chronic renal failure.

4. The client with peripheral vascular disease (PVD) and a history of heart failure may have a low tolerance for exercise due to:

• A. Decreased blood flow.
• B. Increased blood flow.
• C. Decreased pain.
• D. Increased blood viscosity.

Correct answer: A

Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.

5. A client with a history of peptic ulcer disease (PUD) is admitted after vomiting bright red blood several times over the course of 2 hours. In reviewing the laboratory results, the nurse finds the client's hemoglobin is 12 g/dL (120g/L) and the hematocrit is 35% (0.35). Which action should the nurse prepare to take?

• A. Continue monitoring for blood loss
• B. Administer 1,000 mL (1L) of normal saline
• C. Transfuse 2 units of platelets
• D. Prepare the client for emergency surgery

Correct answer: D

Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.
