The nurse evaluates the effects of warfarin by monitoring what lab test?

Choice A rationale

ACE inhibitors can cause teratogenic effects, meaning they can harm a developing fetus. Therefore, precautions should be taken to avoid pregnancy while taking these drugs.

Choice B rationale

Spermicidal jellies alone are not a highly reliable form of contraception. For women taking ACE inhibitors, a more reliable method of contraception is recommended to prevent pregnancy.

Choice C rationale

The minipill, a progestin-only contraceptive, is not the contraceptive of choice when the risk of teratogenic effects from ACE inhibitors is considered. Barrier methods are preferred to avoid potential drug interactions.

Choice D rationale

Barrier contraception, such as condoms or diaphragms, is recommended for women taking ACE inhibitors to prevent pregnancy due to the teratogenic risk associated with these drugs.

Choice A rationale

Thiazide diuretics can lead to hypokalemia, thus a low potassium diet is not recommended. Instead, patients should consume potassium-rich foods to maintain electrolyte balance.

Choice B rationale

Thiazide diuretics increase urine output, which can lead to dehydration. Encouraging increased fluid intake helps to prevent dehydration and maintain proper fluid balance.

Choice C rationale

Thiazide diuretics can cause dizziness or lightheadedness, increasing the risk of falls, especially in elderly patients. Initiating a fall risk protocol is important to ensure patient safety.

Choice D rationale

While exercise is beneficial, thiazide diuretics can cause weakness and dizziness, making it important to assess the patient’s tolerance and monitor their response to physical activity.
