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. The nurse is preparing to administer an antibiotic to a patient who has been receiving the antibiotic for 2 days after a culture was obtained. The nurse notes increased erythema and swelling, and the patient has a persistent high fever of 39°C. What is the nurse’s next action?

• A. Administer the antibiotic as ordered.
• B. Contact the provider to request another culture.
• C. Discuss the need to add a second antibiotic with the provider.
• D. Review the sensitivity results from the patient’s culture.

Correct answer: D

Rationale: In this scenario, the nurse is observing signs of a possible lack of response to the current antibiotic therapy, such as increased erythema, swelling, and persistent high fever. The next appropriate action for the nurse is to review the sensitivity results from the patient’s culture. This step is crucial to determine if the current antibiotic is effective against the causative organism. If the sensitivity results indicate resistance to the current antibiotic, the antibiotic should be discontinued, and the provider should be notified for a change in therapy. Contacting the provider to request another culture is not the immediate priority, as the existing culture results need to be reviewed first. Adding a second antibiotic should only be considered after confirming the sensitivity results, as unnecessary antibiotic use can lead to antimicrobial resistance.

3. When assessing the lower extremities of a client with peripheral vascular disease (PVD), the nurse notes bilateral ankle edema. The edema is related to:

• A. Competent venous valves.
• B. Decreased blood volume.
• C. Increase in muscular activity.
• D. Increased venous pressure.

Correct answer: D

Rationale: The correct answer is 'Increased venous pressure.' In peripheral vascular disease (PVD), impaired blood flow leads to increased venous pressure in the lower extremities, causing fluid to leak out of the blood vessels and accumulate as edema. Choice A, 'Competent venous valves,' is incorrect because in PVD, the venous valves may be incompetent, contributing to venous pooling and edema. Choice B, 'Decreased blood volume,' is incorrect as PVD is associated with impaired blood flow rather than reduced blood volume. Choice C, 'Increase in muscular activity,' is incorrect as it does not directly relate to the development of edema in PVD.

4. A client recently diagnosed with chronic kidney disease (CKD) is receiving discharge instructions from a nurse. Which statements made by the client indicate a correct understanding of the teaching? (Select all that apply.)

• A. I need to ask for an antibiotic when scheduling a dental appointment.
• B. I’ll need to check my blood sugar often to prevent hypoglycemia.
• C. The dose of my pain medication may have to be adjusted.
• D. The need to watch for bleeding with anticoagulants.

Correct answer: A

Rationale: The correct statements indicating a proper understanding of the teaching include the need for antibiotics for dental work, the potential need to adjust pain medication doses, and the importance of monitoring blood sugar levels. The statement about watching for bleeding with anticoagulants is not directly related to CKD and discharge instructions for this condition. Therefore, option A is correct, as it addresses relevant concerns for a client with CKD, while the other options are either unrelated or not specifically mentioned in the scenario.

5. When a patient is receiving high doses of a cephalosporin, which laboratory values will this patient's nurse monitor closely?

• A. Blood urea nitrogen (BUN), serum creatinine, and liver function tests
• B. Complete blood count and electrolytes
• C. Serum calcium and magnesium
• D. Serum glucose and lipids

Correct answer: A

Rationale: When a patient is receiving high doses of a cephalosporin, such as cefazolin, the nurse should closely monitor laboratory values that indicate renal and hepatic function. This includes checking the Blood Urea Nitrogen (BUN) and serum creatinine levels to assess kidney function. Additionally, monitoring liver function tests, such as AST, ALT, ALP, LDH, and bilirubin, is essential as cephalosporins can affect liver enzymes. Therefore, options B, C, and D are incorrect as they do not specifically address the parameters that are most pertinent when administering high doses of cephalosporins.
