Correct Answer: B

Rationale: Furosemide is classified therapeutically as a diuretic. Diuretics are medications used to promote diuresis, which helps the body get rid of excess salt and water. Furosemide is commonly prescribed to treat conditions such as fluid retention and swelling (edema) associated with congestive heart failure, liver disease, or kidney disorders. Choice A, Antidiuretics, is incorrect as Furosemide acts as a diuretic, promoting the production of urine. Choice C, Anticonvulsants, is also incorrect as Furosemide is not used to treat seizures. Choice D, Antidotes, is incorrect as Furosemide is not an antidote but rather a medication used to treat conditions related to fluid retention.

Correct Answer: A

Rationale: In the scenario described, the client is experiencing symptoms of a severe allergic reaction. The priority intervention is to administer epinephrine. Epinephrine acts quickly to reverse the effects of the allergic reaction and can be life-saving in cases of anaphylaxis. Albuterol is used for bronchodilation and may help with respiratory symptoms but is not the first-line treatment for anaphylaxis. Diphenhydramine and prednisone are used for allergic reactions but are not as rapid-acting as epinephrine and should be considered after administering epinephrine in this situation.

Correct Answer: A

Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.

Correct Answer: A

Rationale: The correct answer is A: 'Increase your intake of bananas and oranges.' Furosemide, a loop diuretic, can cause potassium loss leading to hypokalemia. To prevent this, clients should increase their intake of potassium-rich foods, such as bananas and oranges, to replenish potassium levels. Choices B, C, and D are incorrect because limiting calcium-rich foods or avoiding milk is not necessary with Furosemide, and increasing intake of green, leafy vegetables does not specifically address the potential potassium loss associated with this medication.

Correct Answer: C

Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.
