Nursing Elites

1. 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.

2. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

3. Your patient has an order to receive Levothyroxine Sodium 75 mcg daily IV. You have a vial containing 100 mcg available from the pharmacy. According to the package insert, 5 mL of 0.9% sodium chloride is needed to reconstitute. You add the appropriate amount of sodium chloride to the vial. How many mcg of medication are in 1 mL of the vial?

• A. 20 mcg
• B. 15 mcg
• C. 25 mcg
• D. 30 mcg

Correct answer: A

Rationale: After reconstitution, the concentration of Levothyroxine Sodium in the vial is 100 mcg in 5 mL, which equals 20 mcg/mL. Therefore, in 1 mL of the vial, there are 20 mcg of medication.

4. For a patient with asthma, what is the primary purpose of prescribing montelukast?

• A. Relieve acute bronchospasm
• B. Prevent asthma attacks
• C. Thin respiratory secretions
• D. Suppress cough

Correct answer: B

Rationale: Montelukast, a leukotriene receptor antagonist, is primarily prescribed to prevent asthma attacks. It works by reducing inflammation and bronchoconstriction in the airways, thereby helping to control asthma symptoms and prevent exacerbations.

5. A patient with an anxiety disorder is prescribed alprazolam. What is the primary action of this medication?

• A. Increase energy levels
• B. Induce sedation
• C. Elevate mood
• D. Reduce anxiety

Correct answer: D

Rationale: Alprazolam is a benzodiazepine that primarily works by reducing anxiety. It achieves this by enhancing the inhibitory effects of the neurotransmitter GABA in the brain, which leads to a calming effect on the individual. Therefore, the primary action of alprazolam is to decrease anxiety levels rather than increase energy, induce sedation, or elevate mood.
