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: C

Rationale: The correct answer is C: Working. In the working phase, the nurse and patient actively collaborate on achieving goals, such as weight reduction strategies. The nurse assesses, plans, and implements interventions with the patient. During this phase, the focus is on building trust, exploring feelings, and identifying and addressing issues. The other choices are incorrect because in the preinteraction phase (A), there is no direct interaction yet, in the orientation phase (B), the relationship is being established, and in the termination phase (D), the relationship is coming to an end. Thus, the nurse being engaged in weight reduction strategies with the patient indicates that they are in the working phase of the helping relationship.

Correct Answer: C

Rationale: The correct answer is C: Impaired verbal communication. In ALS, motor neurons deteriorate leading to muscle weakness and atrophy, including those involved in speech production. This results in impaired verbal communication. Chronic confusion (A) is not a common manifestation of ALS. Impaired urinary elimination (B) and bowel incontinence (D) are not typically associated with ALS, as it primarily affects motor neurons, not autonomic functions.

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: D

Rationale: The correct answer is D because documenting the patient's pain intensity using a pain scale (8 out of 10) is crucial for assessing the severity of the chest pain. This information helps in determining the appropriate intervention and monitoring the effectiveness of treatment. Choice A is irrelevant as it does not provide any useful information about the patient's condition. Choice B is important for neurological assessment but not specifically related to chest pain. Choice C is not as critical as knowing the current pain level.
