A woman visits a health center requesting oral contraceptives. Which laboratory test is most important for the nurse to assess before the patient begins oral contraceptive therapy?

Vaginal cultures

Complete blood count

Serum potassium level

Pregnancy test

Answer and Explanation

The Correct Answer is C

Choice A reason: Vaginal cultures are not necessary for oral contraceptive therapy. They are used to diagnose infections such as bacterial vaginosis, yeast infection, or sexually transmitted diseases.

Choice B reason: Complete blood count is not essential for oral contraceptive therapy. It is used to measure the number and types of blood cells, such as red blood cells, white blood cells, and platelets.

Choice C reason: Serum potassium level is the most important laboratory test for oral contraceptive therapy. This is because some oral contraceptives can increase the risk of hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can cause serious complications such as cardiac arrhythmias, muscle weakness, and paralysis.

Choice D reason: Pregnancy test is not a laboratory test, but a urine test. It is important to rule out pregnancy before starting oral contraceptive therapy, but it is not the most important test for the nurse to assess.

Correct Answer is B

Explanation

Choice A reason: Antibiotics are not likely to interact with corticosteroids, unless they are aminoglycosides, which can increase the risk of hypokalemia. However, most antibiotics do not affect the metabolism or efficacy of corticosteroids.

Choice B reason: Nonsteroidal anti-inflammatory drugs (NSAIDs) can interact with corticosteroids, as they both have anti-inflammatory and immunosuppressive effects. This can increase the risk of gastrointestinal bleeding, ulceration, and perforation. Therefore, the nurse should monitor the patient for signs of bleeding and advise the patient to avoid taking NSAIDs with corticosteroids.

Choice C reason: Opioid analgesics are not likely to interact with corticosteroids, unless they are codeine, which can decrease the clearance of corticosteroids. However, most opioid analgesics do not affect the metabolism or efficacy of corticosteroids.

Choice D reason: Antidepressants are not likely to interact with corticosteroids, unless they are monoamine oxidase inhibitors (MAOIs), which can increase the risk of hypertension and hypertensive crisis. However, most antidepressants do not affect the metabolism or efficacy of corticosteroids.

A. Inject 20 units of air into the NPH insulin vial. B. Inject 10 units of air into the regular insulin vial. C. Replace the needle for withdrawal with a safety needle. D. Withdraw 10 units of insulin from the regular insulin vial.

Correct Answer is B

Explanation

Choice A reason: This is incorrect because the nurse should inject air into the NPH insulin vial after injecting air into the regular insulin vial. This prevents contamination of the regular insulin with the NPH insulin.

Choice B reason: This is correct because the nurse should inject air into the regular insulin vial first, then into the NPH insulin vial, before withdrawing the regular insulin. This equalizes the pressure in the vials and facilitates the withdrawal of the insulin.

Choice C reason: This is incorrect because the nurse should not replace the needle for withdrawal with a safety needle. The same needle should be used for injecting air and withdrawing insulin from both vials.

Choice D reason: This is incorrect because the nurse should withdraw 10 units of insulin from the regular insulin vial after injecting air into both vials. This prevents mixing of the NPH insulin with the regular insulin in the vial.
