Correct Answer: A

Rationale: The correct answer is A: Use aseptic technique for the insertion site. Aseptic technique is necessary to prevent infection when accessing the intracranial pressure monitoring system. Aseptic technique involves maintaining a sterile field during the insertion process, reducing the risk of introducing pathogens. Using clean technique for cleansing connections (choice B) may introduce contaminants to the insertion site. Sterile technique for cleansing the insertion site (choice C) is not necessary and may be overly stringent. Closing leaks in the tubing with tape (choice D) does not address the prevention of infection at the insertion site.

Correct Answer: C

Rationale: The correct answer is C. Hormonal imbalances are the primary cause of BPH in aging males. As men age, testosterone levels decrease and estrogen levels may increase relative to testosterone, leading to prostate gland growth. This is why hormonal imbalances are more likely the cause of BPH in older males. Explanation of other choices: A: Chronic infection of the urinary tract does not directly cause BPH, although it can lead to similar symptoms such as urinary frequency and urgency. B: Chronic cigarette smoking is not a direct cause of BPH, although it can contribute to overall prostate health and exacerbate symptoms. D: Chronic obstruction of the bladder due to stone is a separate condition from BPH, although it can cause similar urinary symptoms.

Correct Answer: A

Rationale: The correct answer is A because a nursing diagnosis typically consists of two parts: the problem (Risk for Aspiration) and the related factor (reduced level of consciousness). This format helps clearly identify the client's health issue and its cause. Choice B is incorrect as it refers to a nursing diagnosis focusing on the client's response. Choice C is incorrect as it describes an outcome, not a diagnosis. Choice D is incorrect as a nursing diagnosis should be based on evidence, not made without support. Therefore, the correct choice is A due to the structure and clarity it provides in identifying the client's risk.

Correct Answer: A

Rationale: The correct answer is A: once a month after menstruation. Performing BSE at this time helps ensure consistent examination when breasts are less tender or swollen, making it easier to detect abnormalities. Performing it once a month ensures regular monitoring for any changes. Choices B, C, and D are incorrect because they do not provide the recommended frequency or timing for an effective BSE. BSE should be done monthly after menstruation to increase the chances of early detection of breast cancer.

Correct Answer: D

Rationale: Correct Answer: D - Lubricating eye drops Rationale: Lubricating eye drops help prevent complications such as corneal abrasions in patients with Bell's Palsy by keeping the eye moist and preventing dryness. Bell's Palsy can cause difficulty in closing the eye properly, leading to dryness and potential damage to the cornea. Using lubricating eye drops helps maintain eye health. Summary of Incorrect Choices: A: Megavitamin therapy - Not directly related to preventing complications in Bell's Palsy. B: Application of ice to the affected area - Ice may not address eye dryness or prevent corneal abrasions. C: Elastic bandages - Not relevant to preventing complications associated with Bell's Palsy.
