Nursing Elites

1. A 48-year-old man presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.

2. 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.

3. 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.

4. The healthcare professional is caring for a client with heart failure who is receiving digoxin (Lanoxin). Which assessment finding requires immediate intervention?

• A. Heart rate of 58 beats per minute.
• B. Nausea and vomiting.
• C. Blood pressure of 130/80 mm Hg.
• D. Shortness of breath.

Correct answer: B

Rationale: The correct answer is B. Nausea and vomiting are common signs of digoxin toxicity, which can lead to serious complications like dysrhythmias. Prompt intervention is crucial to prevent further harm to the client. Choice A, a heart rate of 58 beats per minute, although slightly lower than normal, may be appropriate for a client on digoxin. Choice C, a blood pressure of 130/80 mm Hg, is within normal limits and does not indicate an immediate need for intervention. Choice D, shortness of breath, is a common symptom in heart failure and requires monitoring but is not as indicative of digoxin toxicity as nausea and vomiting.

5. A client's healthcare provider has ordered a 'liver panel' in response to the client's development of jaundice. When reviewing the results of this laboratory testing, the nurse should expect to review what blood tests? Select one that doesn't apply.

• A. Alanine aminotransferase (ALT)
• B. C-reactive protein (CRP)
• C. Gamma-glutamyl transferase (GGT)
• D. Aspartate aminotransferase (AST)

Correct answer: B

Rationale: A 'liver panel' is a group of blood tests used to evaluate liver function. The components typically include ALT, GGT, and AST. While C-reactive protein (CRP) is a marker of inflammation and not part of a standard liver panel, it may be ordered for other diagnostic purposes.
