Correct Answer: B

Rationale: The correct answer is B: Undercooked ground beef. Escherichia coli is commonly found in undercooked ground beef, especially if it is contaminated during processing. Ground beef must be cooked to a safe internal temperature to kill any harmful bacteria. Improperly home-canned food (choice A) can also cause foodborne illnesses, but E. coli is more commonly associated with undercooked ground beef. Soft cheese (choice C) is often linked to Listeria contamination, not E. coli. Custard (choice D) is a less likely source of E. coli compared to undercooked ground beef.

Correct Answer: A

Rationale: The correct answer is A: Previous birth of large infant. This factor increases the risk of gestational diabetes mellitus due to a history of delivering a large baby, indicating a higher likelihood of insulin resistance in subsequent pregnancies. Maternal age younger than 25 years (B) is not a known risk factor for gestational diabetes. Being underweight prior to pregnancy (C) is actually associated with a decreased risk of gestational diabetes. A previous diagnosis of type 2 diabetes mellitus (D) is a separate condition and does not directly increase the risk of gestational diabetes.

Correct Answer: A

Rationale: Rationale: The correct answer is A because rods are responsible for vision in low light conditions. By ensuring adequate lighting in the patient's room, the nurse can optimize the patient's visual acuity. This will help the patient navigate their environment more safely. Summary: - B is incorrect because dim lighting would further limit the patient's already compromised vision. - C is incorrect as the patient's ability to perceive color may not be affected by rod dysfunction. - D is incorrect as the patient may struggle to see fine details due to rod impairment.

Correct Answer: D

Rationale: The correct answer is D: Normalization of feelings and experiences. Attending a grief support group helps individuals feel validated and understood by others who are going through similar emotions. This normalization can reduce feelings of isolation and provide a sense of belonging, which is crucial in the grieving process. It also allows individuals to recognize that their feelings and experiences are common reactions to loss. Choice A is incorrect because a grief support group focuses more on accepting and processing the new reality rather than incorporating the old life into it. Choice B is incorrect as it suggests maintaining the old life rather than adjusting to a new normal. Choice C is incorrect because the focus of a grief support group is not solely on social skills but on emotional support and coping mechanisms.

Summary of why other choices are incorrect: B. Having someone accompany the patient is important for support but not a strict criteria for discharge. C. While understanding activity restrictions is important, it is not a specific criteria for immediate discharge. D. Understanding care for the biopsy site is essential but not a strict criteria for immediate discharge. E.
