The nurse is teaching a class for clients about over-the-counter (OTC) medications. The nurse determines that education has been effective when the clients make which statement?

Correct Answer: C

Rationale: Reading OTC labels and seeking clarification from a doctor if unclear ensures safe use, reflecting effective education on responsibility. Always calling the doctor is overly cautious-OTC drugs are for self-management. Pharmacists help, but label-reading is primary. Assuming OTC safety ignores risks like ibuprofen's bleeding potential. Label focus empowers clients, balancing autonomy with safety, a key learning outcome.

Correct Answer: D

Rationale: A metallic taste is a common sign of gold salt toxicity, indicating an overdose. Flushing, dizziness, and joint pain are side effects but are not specific to overdose. Gold sodium thiomalate requires careful monitoring to prevent toxicity, and any signs of overdose should be reported immediately.

Correct Answer: A

Rationale: Orthostatic hypotension is a common side effect seen in ACE Inhibitors, Beta Blockers, and Calcium Channel Blockers.

Correct Answer: D

Rationale: The statement "Convenient, safe, economical" does not accurately describe intravenous injection. Intravenous injection is generally considered to be less convenient compared to other routes of administration due to the need for proper training, sterile technique, and close monitoring during drug administration. While it can be effective in delivering drugs quickly and directly into the bloodstream, it is not always the safest or most economical option. Intravenous administration carries risks such as infection, phlebitis, and possible adverse reactions that need to be carefully monitored. Additionally, the cost of intravenous drug administration tends to be higher due to the need for specialized equipment and trained personnel.

Correct Answer: B

Rationale: Before administering a potassium supplement to a patient, it is crucial to check the patient's serum potassium level. This is because if the serum potassium level is already elevated or within the high end of the normal range, giving additional potassium could lead to hyperkalemia, which can be life-threatening. Conversely, if the serum potassium level is low (hypokalemia), then administering potassium supplementation may be necessary to correct the deficiency. Monitoring the serum potassium level helps ensure safe and effective treatment with potassium supplements. It is a critical part of assessing the patient's electrolyte balance and overall health status.
