Nursing Elites

1. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?

• A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
• B. Absent peristalsis and elevated LES pressure
• C. Absent peristalsis and decreased LES pressure
• D. Vigorous peristalsis and decreased LES pressure

Correct answer: C

Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.

2. A patient with asthma is prescribed a corticosteroid inhaler. What is the most important instruction to give to the patient?

• A. Use the inhaler only during asthma attacks.
• B. Rinse the mouth after using the inhaler.
• C. Take a double dose if symptoms worsen.
• D. Avoid using a spacer with the inhaler.

Correct answer: B

Rationale: The most important instruction to give to a patient using a corticosteroid inhaler is to rinse the mouth after each use. This is crucial to prevent the development of oral thrush, a common side effect of corticosteroid inhalers. Failure to rinse the mouth can lead to the overgrowth of yeast in the mouth, causing oral thrush, which can be uncomfortable and require additional treatment. Therefore, reminding patients to rinse their mouth after using the inhaler is essential in preventing this potential complication. Choices A, C, and D are incorrect. Using the inhaler only during asthma attacks may lead to uncontrolled asthma symptoms. Taking a double dose without healthcare provider instruction can result in overdose or side effects. Avoiding a spacer with the inhaler can reduce the effectiveness of delivering the medication to the lungs.

3. 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.

4. A patient with hypertension is prescribed lisinopril. What side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: When a patient is prescribed lisinopril, an ACE inhibitor, the nurse should monitor for hyperkalemia. Lisinopril can cause hyperkalemia by decreasing aldosterone secretion, which leads to potassium retention in the body. Hyperkalemia is a potential side effect of ACE inhibitors and should be closely monitored, as it can have serious consequences such as affecting cardiac function.

5. A patient with chronic pain is prescribed a fentanyl patch. What is the most important instruction for the nurse to provide?

• A. Apply the patch to a different site each time.
• B. Change the patch every 72 hours.
• C. Avoid using additional heating pads over the patch.
• D. Remove the patch before showering.

Correct answer: B

Rationale: The most important instruction for the nurse to provide to a patient prescribed a fentanyl patch is to change the patch every 72 hours. This ensures consistent pain control and prevents complications. It is crucial to rotate the application sites to prevent skin irritation or reactions. Using additional heating pads over the patch should be avoided as it can increase the absorption of the medication, leading to overdose or adverse effects. Removing the patch before showering is not necessary as long as the patch is securely in place.
