Nursing Elites

1. 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.

2. A client is undergoing chemotherapy and is at risk for developing thrombocytopenia. What precaution should the nurse teach the client to minimize the risk of bleeding?

• A. Use a soft-bristled toothbrush.
• B. Engage in daily aerobic exercise.
• C. Take aspirin for headaches.
• D. Use an electric razor for shaving.

Correct answer: A

Rationale: Using a soft-bristled toothbrush is essential for clients at risk of thrombocytopenia to prevent gum bleeding, as their platelet counts may be low. Vigorous brushing with a hard-bristled toothbrush can injure the gums, leading to bleeding, which can be exacerbated in clients with low platelets. Therefore, advising the client to use a soft-bristled toothbrush is a crucial precaution to minimize the risk of bleeding.

3. 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.

4. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which instruction should the nurse provide?

• A. Use oxygen continuously, even while sleeping.
• B. Adjust the oxygen flow rate to 5 liters per minute if short of breath.
• C. Report any signs of difficulty breathing immediately.
• D. Take off the oxygen while eating or drinking.

Correct answer: A

Rationale: The correct instruction for a client with COPD receiving oxygen therapy is to use oxygen continuously, even while sleeping. This is important to ensure adequate oxygenation and optimal respiratory function for clients with COPD. Continuous oxygen therapy helps maintain oxygen levels during sleep, which is crucial for individuals with COPD who may experience nighttime hypoxemia. Therefore, advising the client to use oxygen continuously, even during sleep, is essential in managing COPD and preventing complications associated with oxygen deprivation.

5. The preceptor is orienting a new graduate nurse to the critical care unit. The preceptor asks the new graduate to state symptoms that most likely indicate the beginning of a shock state in a critically ill client. What findings should the new graduate nurse identify?

• A. Warm skin, hypertension, and constricted pupils.
• B. Bradycardia, hypotension, and respiratory acidosis.
• C. Mottled skin, tachypnea, and hyperactive bowel sounds.
• D. Tachycardia, mental status change, and low urine output.

Correct answer: D

Rationale: Tachycardia, mental status change, and low urine output are early indicators of shock. In a critically ill client, these findings suggest a decrease in tissue perfusion. Prompt recognition and intervention are crucial to prevent the progression of shock and its complications.
