Correct Answer: D

Rationale: Rationale: Option D is correct because raising the head of the bed promotes a more natural position for defecation, allowing gravity to assist. This position helps align the rectum and anal canal, making it easier for the patient to have a bowel movement. Administering laxatives (Option C) may help, but adjusting the bed position is a non-invasive and more immediate intervention. Withholding pain medication (Option B) could lead to unnecessary discomfort for the patient. Administering a barium enema (Option A) is not indicated for addressing difficulty with defecation.

Correct Answer: A

Rationale: The correct answer is A: A referral for a mammogram. Given the family history of breast cancer in the patient's father, the nurse should recommend a mammogram as a preventive measure due to increased risk. Mammograms are effective in detecting breast cancer early, especially in individuals with a family history. This can help in early diagnosis and timely intervention if needed. B: Instructions about breast self-examination (BSE) can be helpful, but in this case, a mammogram is a more definitive screening tool for high-risk individuals. C: A referral to a surgeon is not necessary at this point as the patient does not exhibit any symptoms of breast cancer. D: Referral to a support group may be beneficial for emotional support, but the priority should be on proactive screening measures like a mammogram.

Correct Answer: C

Rationale: The correct answer is C: Emotional exhaustion. Dealing with others' pain daily can lead to burnout and emotional exhaustion for the nurse. This can result in decreased empathy and effectiveness in providing care. Healthy practices such as self-care, setting boundaries, and seeking support can help prevent emotional exhaustion. Choice A: Inefficiency in the provision of care is incorrect because emotional exhaustion may affect the quality of care but does not necessarily lead to inefficiency. Choice B: Excessive weight gain is incorrect as it is not directly related to the emotional toll of dealing with others' pain. Choice D: Social withdrawal is incorrect as it is a potential outcome of emotional exhaustion but not the primary concern in this scenario.

Correct Answer: C

Rationale: Step 1: The nurse should inform the patient that most cases of ovarian cancer are considered to be random, with no obvious causation. This is the correct answer because the exact cause of ovarian cancer is not well understood, and the majority of cases are not linked to specific risk factors. Step 2: Choice A is incorrect because the use of oral contraceptives actually decreases the risk of ovarian cancer. Step 3: Choice B is incorrect because tobacco use is not a major risk factor for ovarian cancer. It is primarily associated with lung and other types of cancer. Step 4: Choice D is incorrect because while a family history of ovarian cancer can increase the risk, the majority of women diagnosed with ovarian cancer do not have a family history of the disease.
