Correct Answer: D

Rationale: The correct answer is D: Bradycardia. Pyridostigmine, a cholinesterase inhibitor used in myasthenia gravis, can lead to bradycardia as a side effect. Choice A, constipation, is not a common side effect of pyridostigmine. Choice B, hypertension, is unlikely as pyridostigmine is more likely to cause hypotension. Choice C, muscle weakness, is actually a symptom of myasthenia gravis itself and not a side effect of pyridostigmine.

Correct Answer: A

Rationale: The correct answer is A: Alcohol use during pregnancy. The physical features mentioned are indicative of fetal alcohol syndrome, a condition caused by maternal alcohol consumption during pregnancy. It is crucial for the nurse to inquire about alcohol use as it can help in diagnosing and managing the infant's condition. Choices B, C, and D are incorrect as they are not directly associated with the physical findings described in the newborn, which specifically point towards a potential history of alcohol exposure during pregnancy.

Correct Answer: C

Rationale: The correct statement about breastfeeding is that breastmilk given exclusively for the first 4 to 6 months of life helps avoid the introduction of infection. This practice is recommended by health experts for optimal infant health. Choice A is incorrect because breastfeeding should ideally start within the first hour after birth to stimulate breastmilk production. Choice B is incorrect because breastmilk should be initiated as soon as possible after delivery, not after 24 hours. Choice D is incorrect because while feeding on demand is generally encouraged, it should also follow a schedule to ensure adequate nutrition and growth for the baby.

Correct Answer: A

Rationale: Newborns are at the highest risk for hepatitis B virus due to potential transmission from the mother. The hepatitis B virus can be transmitted from an infected mother to her baby during childbirth. Children born to mothers infected with hepatitis B are at the highest risk of acquiring the infection. Choices B, C, and D are at lower risk compared to a newborn as they are less likely to have been exposed to the virus during childbirth.

Correct Answer: A

Rationale: The correct answer is A because a client with diabetic ketoacidosis (DKA) that is being well-managed and has shown improvement within 24 hours is more stable and can be considered for discharge sooner than those with more acute or unstable conditions. Choice B is incorrect as Tylenol intoxication may require further monitoring and intervention. Choice C is incorrect as a client with an automatic defibrillator and episodes of passing out needs careful evaluation and monitoring. Choice D is incorrect as suspected bacterial meningitis is a serious condition that typically requires a longer hospital stay for treatment and observation.
