Nursing Elites

1. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

2. A client with newly diagnosed hypertension is prescribed enalapril (Vasotec). Which instruction should the nurse provide to the client?

• A. Increase your intake of potassium-rich foods.
• B. Report any persistent cough to your healthcare provider.
• C. Take the medication with a full meal.
• D. Avoid grapefruit juice while taking this medication.

Correct answer: B

Rationale: The correct instruction for the nurse to provide the client taking enalapril (Vasotec) is to report any persistent cough to their healthcare provider. Enalapril can cause a side effect of a persistent cough, and it is essential for the healthcare provider to be notified if this occurs to evaluate the need for a medication adjustment or change. Choices A, C, and D are incorrect. Increasing potassium-rich foods is not specifically related to enalapril use; there is no requirement to take enalapril with a full meal, and avoiding grapefruit juice is more relevant for medications metabolized by the CYP3A4 enzyme, not typically for enalapril.

3. A patient who is diagnosed with cervical cancer that is classified as Tis, N0, M0 asks the nurse what the letters and numbers mean. Which response by the nurse is most appropriate?

• A. The cancer involves only the cervix.
• B. The cancer cells closely resemble normal cells.
• C. Further testing is necessary to determine the spread of the cancer.
• D. Determining the original site of the cervical cancer is challenging.

Correct answer: A

Rationale: The correct response is A: 'The cancer involves only the cervix.' In staging, 'Tis' indicates cancer in situ, which means it is localized to the cervix and not invasive at this time. The differentiation of cancer cells is not part of clinical staging. Since the cancer is in situ, its origin is the cervix. Further testing is not required as the cancer has not spread beyond the cervix. Choice B is incorrect as the staging information provided does not relate to the resemblance of cancer cells to normal cells. Choice C is incorrect because further testing is not necessary as the cancer is localized. Choice D is incorrect because the staging information provided clearly indicates the site of origin as the cervix.

4. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.

5. When planning care for a 16-year-old with appendicitis presenting with right lower quadrant pain, what should the nurse prioritize as a nursing diagnosis?

• A. Imbalanced nutrition: Less than body requirements related to decreased oral intake
• B. Risk for infection related to possible rupture of the appendix
• C. Constipation related to decreased bowel motility and decreased fluid intake
• D. Chronic pain related to appendicitis

Correct answer: B

Rationale: The priority nursing diagnosis for a client with appendicitis is the 'Risk for infection related to possible rupture of the appendix.' Appendicitis carries a risk of the appendix rupturing, which can lead to peritonitis, a life-threatening condition. Preventing infection through timely intervention and surgery is critical in the care of a client with appendicitis, making this nursing diagnosis the priority.
