Nursing Elites

1. A 30-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The clinical presentation of a 30-year-old woman with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria is highly suggestive of type 1 diabetes mellitus. Type 1 diabetes mellitus is characterized by autoimmune destruction of pancreatic beta cells, leading to insulin deficiency and subsequent hyperglycemia. The presence of ketonuria indicates the breakdown of fats for energy due to the lack of insulin. In contrast, type 2 diabetes mellitus typically presents with gradual onset and is often associated with insulin resistance rather than absolute insulin deficiency. Diabetes insipidus is characterized by polyuria and polydipsia but is not associated with hyperglycemia or ketonuria. Hyperthyroidism may present with symptoms like fatigue but does not typically cause hyperglycemia or ketonuria.

2. A patient with depression is prescribed fluoxetine. What is an important side effect for the nurse to monitor?

• A. Weight gain
• B. Bradycardia
• C. Dry mouth
• D. Suicidal thoughts

Correct answer: D

Rationale: When a patient with depression is prescribed fluoxetine, the nurse should be vigilant for the potential side effect of increased risk of suicidal thoughts. Fluoxetine, like other antidepressants, may elevate the risk of suicidal thoughts, particularly during the initial phases of treatment. Monitoring the patient for any indications of heightened depression or suicidal ideation is crucial to ensure appropriate interventions are implemented promptly.

3. A client with chronic pain is prescribed a fentanyl (Duragesic) patch. Which instruction should the nurse provide to the client?

• A. Apply the patch to a clean, dry, and hairless area of the skin.
• B. Use a heating pad over the patch to enhance absorption.
• C. Change the patch daily to maintain effectiveness.
• D. Place the patch on the same site with each application.

Correct answer: A

Rationale: The correct instruction for applying a fentanyl (Duragesic) patch is to place it on a clean, dry, and hairless area of the skin. This ensures proper adhesion of the patch and optimal absorption of the medication. Using a heating pad over the patch is contraindicated as it can increase drug absorption and lead to overdose. Changing the patch daily is necessary for some medications, but fentanyl patches are usually changed every 72 hours to maintain a steady blood level of the medication. Placing the patch on the same site with each application can lead to skin irritation, uneven drug absorption, and should be avoided to allow the skin to recover between applications.

4. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?

• A. Bounding erratic pulse.
• B. Regularly irregular pulse.
• C. Thready irregular pulse.
• D. No palpable pulse.

Correct answer: D

Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.

5. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. 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 combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.
