Correct Answer: D

Rationale: Correct Answer: D - Proper hand hygiene techniques Rationale: 1. Clostridium difficile is mainly spread through contact with contaminated surfaces. 2. Proper hand hygiene is the most effective way to prevent the spread of bacteria. 3. Hand hygiene removes bacteria from hands, reducing the risk of transmission. 4. Appropriate disposal (A) is important but doesn't directly prevent spread. Monthly in-services (B) and mandatory cultures (C) are not as effective as hand hygiene in preventing transmission.

Correct Answer: B

Rationale: The correct answer is B: Mitral valve prolapse. This condition is usually benign during pregnancy because the heart's workload increases, and the mitral valve is a one-way valve that prevents blood from flowing back into the left atrium. Mitral valve prolapse typically does not significantly affect the heart's ability to pump blood efficiently during pregnancy. Rationale: 1. Cardiomyopathy (A) can worsen during pregnancy, leading to complications for both the mother and the fetus. 2. Rheumatic heart disease (C) can cause valve damage, increasing the risk of complications during pregnancy. 3. Congenital heart disease (D) varies in severity and can pose risks during pregnancy, depending on the specific condition. Summary: Mitral valve prolapse is the correct answer as it is less likely to cause significant issues during pregnancy compared to the other options provided.

Correct Answer: B

Rationale: The correct answer is B. By asking the patient to demonstrate the instillation of medications, the nurse can directly assess the patient's ability to self-administer the medications safely and effectively. This method allows for a practical demonstration of skills, which is more reliable than relying solely on verbal descriptions or past experiences. Choices A, C, and D are incorrect because assessing for previous inability, describing the method, or evaluating functional status may not directly demonstrate the patient's competency in self-administering ocular medications.

Correct Answer: A

Rationale: The correct answer is A: Decrease in dysuria. Antimuscarinic medications target muscarinic receptors, which are involved in the contraction of smooth muscle in the bladder. Dysuria, or painful urination, is a common symptom of overactive bladder or bladder spasms, which can be relieved by antimuscarinics. Choices B, C, and D are related to other urinary symptoms such as urgency, frequency, and prostate size, respectively, which are not directly targeted by antimuscarinics. Therefore, only a decrease in dysuria indicates therapeutic effects of the medication.

Correct Answer: A

Rationale: Step 1: Mammograms use low-dose X-rays to create images of the breast tissue. Step 2: The radiation exposure in a mammogram is minimal and considered safe. Step 3: Choice A is correct as it states that mammograms do not use radiation, which is accurate. Step 4: Other choices are incorrect because B wrongly implies that annual mammograms are safe due to low radiation levels, C is incorrect as radiation effects can accumulate over time, and D is incorrect as the amount of radiation in a mammogram is much lower than an hour of sunlight.
