Extract:
Question 1 of 5
A client has been instructed in how to take her nitroglycerin tablets. The nurse giving her instructions knows the client understands the information when she tells her:
Correct Answer: C
Rationale: Headaches may occur after taking nitroglycerin because of vasodilation. The tablets do not need to be refrigerated. The client should carry them with her. The client should contact the physician if repeated doses of nitroglycerin do not relieve the discomfort. Nitroglycerin tablets should be dissolved under the tongue, not swallowed.
Question 2 of 5

Question 3 of 5
The nurse is assessing a client with suspected rheumatoid arthritis. Which finding is most characteristic of this condition?
Correct Answer: A
Rationale: Morning stiffness lasting over 30 minutes is a hallmark of rheumatoid arthritis, reflecting synovial inflammation. Joint pain is symmetrical, fever and weight loss are less specific, and nodules are subcutaneous, not spinal.
Question 4 of 5
An 8-week-old infant has been diagnosed with gastroesophageal reflux. The nurse is teaching the infant's mother to care for the infant at home. Which one of the following statements by the nurse is appropriate regarding the infant's home care?
Correct Answer: D
Rationale: Elevating the child's head to a 30-degree angle is the recommended position for gastroesophageal reflux. The supine position predisposes the child to aspiration. Small, frequent feedings with thickened formula are recommended to minimize vomiting. Antacids should be given at the same time as the feeding to improve their buffering action. The infant should be kept still after feedings to reduce the risk of vomiting and aspiration. Vigorous activities should be carried out before feedings.

A 66-year-old female client has smoked 2 packs of cigarettes per day for 20 years. Her arterial blood gases on room air are as follows: pH 7.35; PO2 70 mm Hg; PCO2 55 mm Hg; HCO3 32 mEq/L. These blood gases reflect:
Correct Answer: B
Rationale: Normal pH with elevated PCO2 and HCO3 indicates compensated respiratory acidosis, common in chronic smokers due to CO2 retention.
