The nurse is caring for a client who has been prescribed chlorpromazine. The nurse correctly identifies which of the client's body system as being associated with the majority of the medications adverse effects?

renal

central nervous system (CNS)

cardiovascular

integumentary

Answer and Explanation

The Correct Answer is B

A. renal: Chlorpromazine is metabolized primarily in the liver and excreted via the kidneys, but it does not commonly cause renal toxicity. The renal system is not the main site of adverse effects for this medication.

B. central nervous system (CNS): Chlorpromazine is an antipsychotic that works by blocking dopamine receptors in the brain. The majority of its adverse effects are CNS-related, including sedation, extrapyramidal symptoms, tardive dyskinesia, and neuroleptic malignant syndrome.

C. cardiovascular: Although chlorpromazine can cause hypotension and prolong the QT interval, cardiovascular effects are less common than CNS effects. They are important to monitor but not the predominant source of adverse reactions.

D. integumentary: Skin-related effects such as photosensitivity or allergic reactions may occur but are relatively rare. The integumentary system is not the primary body system affected by chlorpromazine’s mechanism or side effect profile.

Correct Answer is D

Explanation

A. destroys Helicobacter pylori: Histamine-2 antagonists do not have antibacterial properties and therefore do not eradicate H. pylori. Treating H. pylori requires a combination of antibiotics and acid-suppressing medications in a triple or quadruple therapy regimen.

B. coats and protects the stomach lining: This is the function of gastrointestinal protectants like sucralfate, which form a physical barrier over ulcerated tissue. Histamine-2 antagonists do not create a protective coating but rather work by modulating acid secretion.

C. increases the pH of secreted hydrochloric acid: Histamine-2 antagonists do not change the pH of already secreted acid. Instead, they prevent acid production at the source, thereby reducing the total volume and acidity of gastric secretions over time.

D. reduces the quantity of hydrochloric acid secreted: Histamine-2 antagonists block H2 receptors on gastric parietal cells, which decreases the stimulation of acid production. This leads to a lower volume of hydrochloric acid in the stomach, allowing ulcers to heal more effectively.

A. "Change the tubing frequently, at recommended intervals." B. "Additional insulin requires a separate injection site." C. "Make sure to have your pump calibrated weekly." D. "Watch for signs and symptoms of infection."

Correct Answer is ["A","C","D"]

Explanation

A. "Change the tubing frequently, at recommended intervals.": Insulin pump users must change tubing and infusion sites every 2–3 days to prevent occlusion, insulin degradation, or infection. Proper maintenance helps ensure consistent insulin delivery and reduces complications.

B. "Additional insulin requires a separate injection site.": External insulin pumps can deliver both basal and bolus doses through the same subcutaneous site, eliminating the need for separate injections. Therefore, additional insulin dosing does not require a different site unless the pump malfunctions.

C. "Make sure to have your pump calibrated weekly.": Many pumps require regular calibration or confirmation of accurate delivery, especially if integrated with a continuous glucose monitor. Weekly checks help ensure safe and effective insulin administration.

D. "Watch for signs and symptoms of infection.": Infection is a risk due to the constant presence of subcutaneous tubing. Clients must inspect the site regularly for redness, swelling, warmth, or discharge and practice proper hygiene when changing the site to prevent complications.
