A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?

Stop the oral contraceptive immediately.

Take the medications at least 12 hours apart.

Use an additional form of contraception.

Avoid prolonged exposure to direct sunlight.

Answer and Explanation

The Correct Answer is C

Choice A reason: Stopping the oral contraceptive immediately is not necessary and may increase the risk of unintended pregnancy. Erythromycin can reduce the effectiveness of oral contraceptives by interfering with their metabolism, but it does not make them completely ineffective.

Choice B reason: Taking the medications at least 12 hours apart is not sufficient to prevent the interaction between erythromycin and oral contraceptives. The interaction can occur regardless of the timing of the doses.

Choice C reason: Using an additional form of contraception is the best instruction for the client who is taking an oral contraceptive and erythromycin. This can prevent pregnancy in case the oral contraceptive fails due to the interaction with erythromycin. The additional form of contraception should be non-hormonal, such as a barrier method or a copper intrauterine device.

Choice D reason: Avoiding prolonged exposure to direct sunlight is a good advice for anyone taking erythromycin, as it can cause photosensitivity and increase the risk of sunburn. However, this is not related to the interaction with oral contraceptives and does not affect their efficacy.

Correct Answer is A

Explanation

Choice A reason: Tetracycline HCl can make the skin more sensitive to sunlight and increase the risk of sunburn. Therefore, the client should avoid exposure to direct sunlight and use sunscreen or protective clothing while taking the drug.

Choice B reason: Orange juice is acidic and can decrease the absorption of tetracycline HCl in the GI tract. Therefore, the client should not take the drug with orange juice or other acidic beverages.

Choice C reason: Serum drug levels are not routinely monitored for tetracycline HCl, as there is no established therapeutic range or toxicity level for this drug. Therefore, the client does not need to return to the clinic weekly to obtain serum drug levels.

Choice D reason: Milk and antacids can bind to tetracycline HCl and reduce its effectiveness. Therefore, the client should not take the drug with milk or antacids or within 2 hours of consuming them.

A. Hypertension. B. Bradycardia. C. Pupillary constriction. D. Scratchy throat.

Correct Answer is D

Explanation

Choice A reason: Hypertension is not a typical sign of an allergic reaction to piperacillin-tazobactam, which is an antibiotic. It may be caused by other factors, such as pain, anxiety, or renal impairment. The nurse should monitor the client's blood pressure and report any abnormal findings.

Choice B reason: Bradycardia is not a common or serious side effect of piperacillin-tazobactam. It may be related to other medications, such as beta-blockers, or underlying cardiac conditions. The nurse should check the client's pulse and rhythm and report any changes.

Choice C reason: Pupillary constriction is not associated with piperacillin-tazobactam or an allergic reaction. It may be caused by other drugs, such as opioids, or neurological disorders. The nurse should assess the client's level of consciousness and pupillary response.

Choice D reason: Scratchy throat is a possible sign of anaphylaxis, which is a severe and potentially fatal allergic reaction to piperacillin-tazobactam or any other drug. Other symptoms may include hives, swelling, wheezing, or hypotension. The nurse should stop the infusion immediately and call for help.
