1. A new mother is at the clinic with her 4-week-old for a well-baby check-up. The nurse should tell the mother to anticipate that the infant will demonstrate which milestone by 2 months of age?

A. Turns from side to back and returns
B. Consistently returns smiles to mother
C. Finds hands and plays with fingers
D. Holds head up and supports weight with arms

Correct answer: B

Rationale: The correct answer is B because social smiling is a developmental milestone typically expected around 2 months of age. At this stage, infants start to engage more with their caregivers and show positive emotional responses. The other choices are incorrect. Choice A describes a motor skill that usually emerges later. Choice C involves more coordination and exploration, which is not typically seen by 2 months. Choice D relates to head control and arm strength, which also develop progressively but may not be fully achieved by 2 months.

2. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

A. 50
B. 67
C. 57
D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.

3. The nurse is preparing a client for discharge following a myocardial infarction. What should the nurse prioritize in the discharge instructions?

A. Warning signs of a potential heart attack
B. Importance of medication adherence
C. Follow-up appointment details
D. All of the above

Correct answer: D

Rationale: When preparing a client for discharge after a myocardial infarction, the nurse should prioritize providing comprehensive instructions. This includes educating the client about warning signs of a potential heart attack to recognize symptoms early, stressing the importance of medication adherence for optimal recovery and prevention of further cardiac events, and ensuring understanding of follow-up appointment details for ongoing monitoring and care. All these aspects are crucial in preventing complications and promoting the client's well-being. Therefore, selecting 'All of the above' as the correct answer is the most appropriate choice. Choices A, B, and C are all essential components of a holistic discharge plan for a client post-myocardial infarction.

4. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?

A. Check blood pressure.
B. Assess heart rate.
C. Monitor respiratory rate.
D. Measure oxygen saturation.

Correct answer: B

Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.

5. When reconstituted, how many milligrams are in each milliliter of solution?

A. 300 mg/mL
B. 350 mg/mL
C. 450 mg/mL
D. 400 mg/mL

Correct answer: D

Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.
