Nursing Elites

1. Which of the following clients should refrain from therapy with the thiazide diuretic hydrochlorothiazide?

• A. a client with renal impairment
• B. a client with hypertension
• C. a client with diabetes mellitus, type II
• D. a client with renal calculi (kidney stones)

Correct answer: C

Rationale: The correct answer is a client with diabetes mellitus, type II. Thiazide diuretics like hydrochlorothiazide can cause metabolic abnormalities, including elevated blood glucose levels. This increase is linked to diuretic-induced potassium deficiency, which reduces insulin secretion, leading to higher plasma glucose levels. Thiazides are commonly used in clients with renal impairment and hypertension. Moreover, thiazides decrease calcium excretion, reducing the risk of renal calculi, so it is not contraindicated for clients with kidney stones. Therefore, clients with diabetes mellitus, type II should avoid therapy with hydrochlorothiazide due to the potential adverse effects on blood glucose levels.

2. The new mother asks why her baby has lost weight since he was born. The best explanation of the weight loss is:

• A. The baby is dehydrated due to polyuria.
• B. The baby is hypoglycemic due to lack of glucose.
• C. The baby is allergic to the formula the mother is giving him.
• D. The baby can lose up to 10% of weight due to meconium stool, loss of extracellular fluid, and initiation of breastfeeding.

Correct answer: D

Rationale: After birth, newborns can lose weight due to meconium stool, loss of extracellular fluid, and the initiation of breastfeeding. This weight loss is a normal and expected physiological process, and infants can lose up to 10% of their birth weight during this period. There is no indication of dehydration (polyuria), hypoglycemia (lack of glucose), or allergy to the formula as reasons for weight loss in newborns. Therefore, answers A, B, and C are incorrect. Answer D provides the most accurate explanation for the observed weight loss in the newborn.

3. While the client is receiving quinidine, the nurse should monitor the ECG for:

• A. Peaked P wave
• B. Elevated ST segment
• C. Inverted T wave
• D. Prolonged QT interval

Correct answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.

4. An infant weighs 7 pounds at birth. What is the expected weight by 1 year of age?

• A. 10 pounds
• B. 12 pounds
• C. 18 pounds
• D. 21 pounds

Correct answer: D

Rationale: A birth weight of 7 pounds typically triples by the age of 1 year, resulting in an expected weight of 21 pounds. This significant weight gain is a normal growth pattern for infants as they usually experience rapid growth in the first year of life. Choices A, B, and C are incorrect because they do not account for the usual growth rate of an infant in the first year. Infants commonly triple their birth weight by the age of 1, making 21 pounds the expected weight.

5. James returns home from school angry and upset because his teacher gave him a low grade on an assignment. After returning home from school, he kicks the dog. This coping mechanism is known as:

• A. denial
• B. suppression
• C. displacement
• D. fantasy

Correct answer: C

Rationale: The correct answer is 'displacement.' Displacement is a defense mechanism where emotions or impulses are transferred from their original source to a substitute target. In this scenario, James is displacing his anger from his teacher onto the dog. Choice A, 'denial,' involves refusing to acknowledge an unpleasant reality. Choice B, 'suppression,' is the conscious effort to push unwanted thoughts out of awareness. Choice D, 'fantasy,' refers to imagining scenarios that fulfill one's desires but are not based in reality.
