A 33-year-old man with a history of asthma comes into the emergency department after getting stung by a bee. The treating physician wants to give epinephrine subcutaneously. Which of the following contraindications to this medication is noted?

Correct Answer: B

Rationale: Epinephrine treats anaphylaxis but risks exacerbating narrow-angle glaucoma . It dilates pupils, increasing intraocular pressure. Diabetes , pulmonary failure , thyroid disease , and age (E) aren't absolute contraindications. Glaucoma's risk requires caution in this asthmatic.

Correct Answer: B

Rationale: Aspirin's use for pain involves anti-inflammatory and analgesic properties, but it risks GI irritation. Enteric-coated capsules minimize this by dissolving in the intestine, not the stomach, reducing bleeding risk—an accurate statement. High doses are true for anticoagulation, not pain relief, where lower doses suffice. Herbs like garlic and ginger increase bleeding risk, not inflammation relief, making it dangerous advice. Low doses (choice D, 325 mg) primarily prevent clotting, not significantly reduce inflammation, which requires higher doses. Choice B correctly reflects a practical measure to enhance aspirin's safety profile for pain management.

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.

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: A

Rationale: A. You must limit certain types of food or concurrent administration of certain types of drugs: Some foods can interact with certain medications, either reducing their effectiveness or causing potentially harmful side effects. Therefore, it may be necessary to limit or avoid specific foods when taking certain medications.
