Extract:
Question 1 of 5
The nurse is monitoring a client’s EKG strip and notes coupled premature ventricular contractions greater than 10 per minute.
Correct Answer: D
Rationale: Lidocaine is the drug of choice for frequent or coupled PVCs, as it suppresses ventricular arrhythmias that could lead to ventricular tachycardia. Atropine treats bradycardia, isoproterenol is used for heart block, and verapamil is a calcium-channel blocker for supraventricular arrhythmias.
Question 2 of 5
The mother of a 10-year-old boy with IDDM (insulin-dependent diabetes mellitus) calls to discuss the child’s self-monitoring blood glucose (SMBG) home readings. He is being tightly regulated with a combination of NPH and regular insulin before breakfast and supper. The past two mornings his blood sugar readings were 220 mg/dL and 210 mg/dL. The nurse should advise the mother to
Correct Answer: B
Rationale: High morning blood sugars suggest rebound hyperglycemia (Somogyi effect) from nocturnal hypoglycemia, requiring nighttime glucose checks. Options A, C, and D are premature: continuing the regimen ignores the issue, and adjusting insulin or snack timing requires confirmation.
Question 3 of 5
An obstetrical client elects to have epidural anesthesia with Marcaine. After the epidural anesthesia is given, the nurse should monitor the client for signs of:
Correct Answer: C
Rationale: Marcaine (bupivacaine) can cause vasodilation, leading to postural hypotension. Seizures, respiratory depression, and hematuria are less common.
Question 4 of 5
The client is taking streptomycin, isoniazid, and rifampin (Rimactane). Which statement indicates toxicity to isoniazid?
Correct Answer: B
Rationale: Isoniazid can cause peripheral neuropathy, manifesting as sharp leg pains. Tinnitus is linked to streptomycin, orange urine to rifampin, and color vision issues are unrelated.
Question 5 of 5
The nurse evaluates the nutritional intake of a 16-year-old girl at a camp for adolescents. The girl eats all of the food provided to her at the camp cafeteria. Each of the day's three meals contains foods from all areas of the food pyramid, and each meal averages about 900 calories and 3 mg of iron. The girl has been menstruating monthly for about two years. Which of the following descriptions, if made by the nurse, BEST describes the girl's intake if her weight is appropriate for her height?
Correct Answer: C
Rationale: 900 × 3 = 2,700 calories/day and women need 1,200-1,500 kcal/day (men need 1,500-1,800 kcal/day); 3 mg × 3 = 9 mg/day of iron and women need 15 mg/day of iron (men need 10 mg/day); with pregnancy 30 mg/day required
