Nursing Elites

1. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

2. A client with chronic obstructive pulmonary disease (COPD) is receiving supplemental oxygen. The client reports feeling short of breath and has a respiratory rate of 28 breaths per minute. What should the nurse do first?

• A. Increase the oxygen flow rate
• B. Notify the healthcare provider
• C. Administer a bronchodilator
• D. Elevate the head of the bed

Correct answer: D

Rationale: Elevating the head of the bed promotes lung expansion and improves oxygenation, making it the priority intervention for a client with shortness of breath. This position helps in maximizing lung expansion and aiding ventilation-perfusion matching in patients with COPD. Increasing the oxygen flow rate may be necessary but should come after optimizing the client's positioning. Notifying the healthcare provider and administering a bronchodilator are not the initial interventions for addressing shortness of breath in a client with COPD.

3. What is the expected outcome of prescribing a proton pump inhibitor to a client with a peptic ulcer?

• A. Promote healing of the gastric mucosa.
• B. Neutralize the effects of stomach acid.
• C. Inhibit the growth of Helicobacter pylori.
• D. Reduce gastric acid secretion.

Correct answer: D

Rationale: The correct answer is D: Reduce gastric acid secretion. Proton pump inhibitors (PPIs) work by reducing gastric acid secretion, which helps prevent further irritation of the gastric mucosa and allows ulcers to heal. While promoting healing of the gastric mucosa (Choice A) is an indirect outcome of reducing gastric acid secretion, the primary mechanism of PPIs is to lower acid levels. Choice B, neutralizing the effects of stomach acid, is typically associated with antacids, not PPIs. Inhibiting the growth of Helicobacter pylori (Choice C) is usually achieved with antibiotics, not PPIs.

4. After placing a stethoscope to auscultate S1 and S2 heart sounds, what should the nurse do to check for an S3 heart sound?

• A. Switch to the diaphragm of the stethoscope to hear any abnormal sounds
• B. Listen with the bell of the stethoscope at the same location
• C. Listen at a different location over the aortic area
• D. Switch to the apical area and reassess for S3 sounds

Correct answer: B

Rationale: To assess for an S3 heart sound, the nurse should listen with the bell of the stethoscope. An S3 heart sound is often low-pitched and best heard with the bell. Choice A is incorrect because switching to the diaphragm is not ideal for detecting low-pitched sounds like an S3. Choice C is incorrect as the S3 heart sound is best heard over the apex of the heart, not the aortic area. Choice D is incorrect because moving to the apical area is appropriate, but the nurse should specifically use the bell of the stethoscope to listen for S3 sounds.

5. During a thyroid storm, what is the nurse's priority intervention for a client experiencing increased heart rate and tremors?

• A. Administer antithyroid medications as prescribed.
• B. Administer a beta-blocker to control the heart rate.
• C. Monitor the client's temperature closely.
• D. Prepare the client for an emergency thyroidectomy.

Correct answer: A

Rationale: The correct answer is to administer antithyroid medications as prescribed during a thyroid storm. Antithyroid medications help control the overproduction of thyroid hormones, which is crucial in managing symptoms such as increased heart rate and tremors. These symptoms can be life-threatening if not promptly addressed. Administering a beta-blocker (Choice B) may help control the heart rate, but addressing the underlying cause with antithyroid medications is the priority. Monitoring the client's temperature (Choice C) is important but not the priority intervention during a thyroid storm. Lastly, preparing the client for an emergency thyroidectomy (Choice D) is not the initial intervention for managing symptoms of a thyroid storm.
