A nurse is reviewing the medication metformin with a client who has diabetes. Which of the following side effects should the nurse discuss?

Correct Answer: A

Rationale: The correct answer is A: Gastrointestinal upset. Metformin can cause gastrointestinal upset, especially when first starting therapy. It is important to take it with food to reduce these effects. Increased appetite (choice B) and weight loss (choice C) are not common side effects of metformin but may occur due to improved blood sugar control. Frequent urination (choice D) is a symptom of uncontrolled diabetes and not a side effect of metformin.

Correct Answer: A

Rationale: The correct sequence of events for administering regular insulin and NPH insulin begins with inspecting the vials for contamination to ensure patient safety. Rolling the NPH insulin vial between the hands to mix and injecting air into the NPH insulin vial should follow the inspection step. Afterward, the nurse should inject air into the regular insulin vial and then withdraw the regular insulin first. Option A is the correct answer as it outlines the initial crucial step in the administration process. Option B is incorrect as it provides the incorrect order of withdrawing the insulins. Option C is incorrect as injecting air into the NPH insulin vial should come after inspecting the vials. Option D is incorrect as rolling the NPH insulin vial should be done after inspecting the vials and injecting air into the NPH insulin vial.

Correct Answer: C

Rationale: The correct answer is C: Hypokalemia. Furosemide is a loop diuretic that works by increasing the excretion of water and electrolytes, particularly potassium. Therefore, the nurse should monitor for hypokalemia, as low potassium levels can lead to various complications such as cardiac dysrhythmias. Choice A, increased urinary output, is an expected effect of furosemide due to its diuretic action but is not a side effect needing monitoring. Ototoxicity (Choice B) is a potential adverse effect of other medications like aminoglycoside antibiotics, not furosemide. Hypoglycemia (Choice D) is not a common side effect associated with furosemide administration.

Correct Answer: B

Rationale: The correct answer is B: 'Drink at least 2 liters of water per day.' Clients taking allopurinol should be instructed to drink plenty of water to prevent kidney stones, a potential side effect of the medication. Option A is incorrect because allopurinol is usually taken without regard to meals. Option C is not directly related to the teaching about allopurinol, as it pertains more to dietary management of gout. Option D is also unrelated to allopurinol use for gout.

Correct Answer: B

Rationale: Correct Answer: B. Ceftriaxone should be reconstituted with sterile water, not saline. Reconstituting it with normal saline can result in a chemical interaction and precipitation of the drug. Administering the medication over 30 minutes (choice C) is not necessary as ceftriaxone is usually given as an intravenous bolus or drip over a shorter period. Monitoring for signs of toxicity (choice D) is important but not the immediate action required for preparing the medication. The priority is to ensure proper reconstitution with the appropriate solvent, which is sterile water.
