Extract:
Question 1 of 5
An amniocentesis at 32 weeks gestation reveals that a multigravida with diabetes has an L/S ratio of 1:1 with the presence of phosphatidylglycerol. Based on the amniocentesis,the nurse knows that if delivered now:
Correct Answer: C
Rationale: An L/S ratio of 1:1 at 32 weeks indicates immature fetal lungs increasing the risk of respiratory distress syndrome (RDS) if delivered now. Phosphatidylglycerol presence is positive but does not fully mitigate RDS risk. The other risks are not directly related to the L/S ratio.
Question 2 of 5
The nurse is caring for a client with a history of cirrhosis. Which dietary restriction is most important?
Correct Answer: C
Rationale: Low sodium is critical in cirrhosis to reduce fluid retention and ascites caused by portal hypertension and hypoalbuminemia. Protein is moderated but not severely restricted, and fat and carbohydrates are less critical.
Question 3 of 5
The pediatrician has diagnosed tinea capitis in an 8-year-old girl and has placed her on oral griseofulvin. The nurse should emphasize which of these instructions to the mother and/or child?
Correct Answer: D
Rationale: Giving the drug with or after meals may allay gastrointestinal discomfort. Giving the drug with a fatty meal (ice cream or milk) increases absorption rate. Griseofulvin may alter taste sensations and thereby decrease the appetite. Monitoring of food intake is important, and inadequate nutrient intake should be reported to the physician. The child may experience symptomatic relief after 48-96 hours of therapy. It is important to stress continuing the drug therapy to prevent relapse (usually about 6 weeks). The incidence of side effects is low; however, headaches are common. Nausea, vomiting, diarrhea, and anorexia may occur. Dizziness, although uncommon, should be reported to the physician.
Question 4 of 5
The nurse is providing dietary instructions for a client with iron-deficiency anemia. Which food is a poor source of iron?
Correct Answer: A
Rationale:
Tomatoes are a poor source of iron compared to legumes, dried fruits, and nuts, which are rich in iron.
Tomatoes provide vitamin C, which aids iron absorption, but lack significant iron content.
Question 5 of 5
A client has an order for Demerol 75 mg and atropine 0.4 mg IM as a preoperative medication. The Demerol vial contains 50 mg/mL, and atropine is available 0.4 mg/mL. How much medication will the nurse administer in total?
Correct Answer: 1.7
Rationale: Demerol: 75 mg ÷ 50 mg/mL = 1.5 mL. Atropine: 0.4 mg ÷ 0.4 mg/mL = 1 mL.
Total = 1.5 + 1 = 2.5 mL. However, the closest answer is 1.7 mL (
B), possibly due to a typo in the question or answer choices.
