Nursing Elites

1. A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. How many mL should the nurse administer per dose? (Round to the nearest tenth)

• A. 2.6 mL
• B. 2.2 mL
• C. 3.5 mL
• D. 5.0 mL

Correct answer: A

Rationale: The correct calculation is as follows: The toddler's weight in kg is 13 kg (28.6 lb / 2.2 lb/kg). The total daily dose is 260 mg (20 mg x 13 kg). Therefore, the dose per administration is 130 mg (260 mg / 2). Given the concentration of 250 mg/5 mL, the dose in mL is 2.6 mL (130 mg / (250 mg/5 mL)). Therefore, the nurse should administer 2.6 mL per dose. Choice B, 2.2 mL, is incorrect as it does not reflect the correct calculation. Choices C and D, 3.5 mL and 5.0 mL, are also incorrect and do not align with the accurate dosage calculation based on the given scenario.

2. A nurse is caring for a client in preterm labor who is receiving magnesium sulfate. Which of the following is an indication of magnesium toxicity?

• A. Blood glucose of 160 mg/dL
• B. Urine output of 20 mL/hour
• C. Systolic BP of 140 mm Hg
• D. Respiratory rate of 20/min

Correct answer: B

Rationale: The correct answer is B: Urine output of 20 mL/hour. Urine output below 30 mL/hour is a sign of magnesium toxicity due to the risk of accumulation in the body. Choices A, C, and D are not indicative of magnesium toxicity. Elevated blood glucose, systolic blood pressure, and normal respiratory rate are not specific signs of magnesium toxicity.

3. A nurse is assessing a client with pericarditis. Which of the following findings is the priority for the nurse to report?

• A. Paradoxical pulse
• B. Dependent edema
• C. Pericardial friction rub
• D. Substernal chest pain

Correct answer: A

Rationale: A paradoxical pulse is a sign of cardiac tamponade, a life-threatening complication of pericarditis that requires immediate intervention. It results from decreased cardiac output due to increased pressure in the pericardial sac. Reporting this finding promptly allows for timely treatment to prevent further deterioration. Dependent edema and substernal chest pain are common in pericarditis but are not as urgent as a paradoxical pulse. A pericardial friction rub is a classic finding in pericarditis and indicates inflammation but is not as critical as a paradoxical pulse.

4. A nurse is providing education to a client in the first trimester of pregnancy. What information should the nurse include regarding the cause of indigestion and heartburn?

• A. Estrogen causes increased appetite
• B. Progesterone causes relaxation of the cardiac sphincter allowing acid to reflux
• C. HCG hormone leads to increased gastric acidity
• D. The uterus compresses the stomach early in pregnancy

Correct answer: B

Rationale: The correct answer is B. Progesterone causes relaxation of the smooth muscles in the body, including the cardiac sphincter. This relaxation allows stomach acid to reflux into the esophagus, leading to heartburn during pregnancy. Choices A, C, and D are incorrect because they do not directly relate to the physiological mechanism that causes heartburn during pregnancy. Estrogen causing increased appetite (Choice A) is not directly linked to heartburn. HCG hormone increasing gastric acidity (Choice C) is not the primary cause of heartburn during pregnancy. The uterus compressing the stomach early in pregnancy (Choice D) may contribute to feelings of fullness or bloating but is not the main cause of heartburn.

5. Which of the following characteristics would indicate true labor in a client?

• A. Contractions are irregular and painless
• B. Fetus moves to an anterior position
• C. Bloody show is not present
• D. Contractions are regular in frequency

Correct answer: D

Rationale: The correct answer is D. True labor is characterized by regular contractions that increase in intensity and frequency. These contractions lead to cervical dilation and effacement, signaling the onset of labor. Choice A is incorrect because true labor contractions are regular and painful, not irregular and painless. Choice B is irrelevant to determining true labor. Choice C is also unrelated as the presence or absence of a bloody show does not definitively indicate true labor.
