Nursing Elites

1. Before administering an antibiotic that can cause nephrotoxicity, which lab value is most important for the PN to review?

• A. Hemoglobin and Hematocrit
• B. Serum Calcium
• C. Serum Creatinine
• D. WBC

Correct answer: C

Rationale: Serum creatinine is the most important lab value to review before administering an antibiotic that can cause nephrotoxicity. This is because serum creatinine is a key indicator of kidney function. An elevated serum creatinine level may indicate impaired renal function, and administering nephrotoxic drugs in such situations can further damage the kidneys. Monitoring serum creatinine levels helps healthcare providers assess renal function and make informed decisions regarding drug administration. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity, making them less crucial in this scenario. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels are more related to bone health and nerve function, and WBC count is associated with immune response, none of which directly reflect kidney function or the risk of nephrotoxicity.

2. What is the most common cause of acute pancreatitis?

• A. Gallstones
• B. Alcohol abuse
• C. Hypertriglyceridemia
• D. Infection

Correct answer: A

Rationale: The correct answer is A: Gallstones. Gallstones are the most common cause of acute pancreatitis as they obstruct the pancreatic duct, leading to inflammation. While alcohol abuse (Choice B) can also cause pancreatitis, gallstones are more prevalent. Hypertriglyceridemia (Choice C) is a less common cause of acute pancreatitis compared to gallstones. Infection (Choice D) is not a primary cause of acute pancreatitis; gallstones are the leading etiology.

3. An older client is admitted to the psychiatric unit for assessment of a recent onset of dementia. The PN notes that in the evening this client often becomes restless, confused, and agitated. Which intervention is most important for the PN to implement?

• A. Ask family members to remain with the client in the evenings from 5 to 8 pm
• B. Administer a prescribed PRN benzodiazepine at the onset of a confused state
• C. Ensure that the client is assigned to a room close to the nurses' station
• D. Postpone administration of nighttime medications until after 11 pm

Correct answer: C

Rationale: Sundowning, a phenomenon where dementia symptoms worsen in the evening, can be managed by ensuring the client is close to the nurses' station for frequent monitoring and quick intervention, if necessary. This reduces the risk of harm and helps manage agitation. Asking family members to remain with the client may not always be feasible and does not address the need for close monitoring. Administering benzodiazepines should not be the first-line intervention for sundowning as it can increase the risk of falls and other adverse effects. Postponing medication administration may disrupt the client's routine and potentially worsen symptoms.

4. The nurse is teaching a pregnant client how to distinguish prelabor contractions from true labor contractions. Which statement about prelabor contractions is accurate?

• A. They are irregular
• B. They are usually felt in the abdomen
• C. They start in the back and radiate to the abdomen
• D. They become more intense during walking

Correct answer: B

Rationale: The correct statement about prelabor contractions (Braxton Hicks contractions) is that they are usually felt in the abdomen. They are irregular in nature and do not intensify with movement. Choice A is incorrect because prelabor contractions are irregular, not regular. Choice C is incorrect as prelabor contractions do not start in the back and radiate to the abdomen. Choice D is incorrect as prelabor contractions do not become more intense during walking.

5. In which type of cardiomyopathy does septal involvement occur?

• A. Congestive
• B. Dilated
• C. Hypertrophic
• D. Restrictive

Correct answer: C

Rationale: Septal involvement is a characteristic feature of hypertrophic cardiomyopathy, where the septal wall of the heart thickens. This thickening can obstruct blood flow out of the heart, leading to complications such as arrhythmias and heart failure. This differentiates it from other types of cardiomyopathy. In congestive cardiomyopathy (choice A), the heart's chambers become enlarged and weakened, but there is no specific mention of septal involvement. Dilated cardiomyopathy (choice B) involves dilation and impaired contraction of the heart chambers, not specifically septal thickening. Restrictive cardiomyopathy (choice D) is characterized by stiffening of the heart muscle, affecting its ability to fill properly, without direct involvement of the septum.
