Nursing Elites

1. Which finding would necessitate an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy?

• A. Weight loss of 2 lb (1 kg)
• B. Positive urine pregnancy test
• C. Hemoglobin level of 10.4 g/dL
• D. Complaints of nausea and anorexia

Correct answer: B

Rationale: A positive urine pregnancy test would require an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy due to the teratogenic effects of ribavirin. Ribavirin needs to be discontinued immediately to prevent harm to the fetus. The other options, weight loss, hemoglobin level, and complaints of nausea and anorexia, are common adverse effects of the prescribed regimen and may necessitate interventions such as patient education or supportive care, but they would not mandate an immediate cessation of therapy as in the case of a positive pregnancy test.

2. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?

• A. Stroke volume
• B. Cardiac output
• C. Venous pressure
• D. Left ventricular functioning

Correct answer: D

Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.

3. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

4. Following a diagnosis of acute glomerulonephritis (AGN) in their 6-year-old child, the parent remarks, 'We just don't know how he caught the disease!' The nurse's response is based on an understanding that

• A. AGN is a streptococcal infection that involves the kidney tubules
• B. The disease is easily transmissible in schools and camps
• C. The illness is usually associated with chronic respiratory infections
• D. It is not 'caught' but is a response to a previous B-hemolytic strep infection

Correct answer: D

Rationale: Acute glomerulonephritis (AGN) is generally considered an immune-complex disease in response to a previous B-hemolytic streptococcal infection, typically occurring 4 to 6 weeks prior. It is not an infectious disease but a noninfectious renal condition. Therefore, the parent's belief that the child 'caught' the disease is inaccurate. Choice A is incorrect because AGN is not a direct streptococcal infection involving the kidney tubules but an immune response to a prior streptococcal infection. Choice B is incorrect as AGN is not easily transmissible in schools and camps. Choice C is incorrect as AGN is not usually associated with chronic respiratory infections but with a previous streptococcal infection.

5. The nurse is caring for a 2-year-old who is being treated with chelation therapy, calcium disodium edetate, for lead poisoning. The nurse should be alert for which of the following side effects?

• A. Neurotoxicity
• B. Hepatomegaly
• C. Nephrotoxicity
• D. Ototoxicity

Correct answer: C

Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.
