1. Which electrolyte imbalance is most concerning in a patient on furosemide?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.

2. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

3. A charge nurse is teaching a newly licensed nurse about clients designating a health care proxy. Which of the following information should the charge nurse include?

• A. The proxy should make health care decisions for the client regardless of the client's ability to do so
• B. The proxy can make financial decisions if the need arises
• C. The proxy can make treatment decisions if the client is under anesthesia
• D. The proxy should manage legal issues for the client

Correct answer: C

Rationale: The correct answer is C because the health care proxy can make treatment decisions for the client if the client is under anesthesia. This aligns with the concept of durable power of attorney for health care, where the proxy is authorized to make health care decisions when the client is unable to do so. Choices A, B, and D are incorrect. Choice A is incorrect because the proxy should make health care decisions only when the client is unable to do so. Choice B is incorrect as financial decisions are not typically within the scope of a health care proxy. Choice D is incorrect as managing legal issues is not the primary role of a health care proxy.

4. How should a healthcare provider care for a patient with a tracheostomy?

• A. Clean the tracheostomy site daily
• B. Change the tracheostomy ties daily
• C. Suction the tracheostomy regularly
• D. Provide humidified oxygen

Correct answer: C

Rationale: Suctioning the tracheostomy regularly is crucial in caring for a patient with a tracheostomy as it helps keep the airway clear of secretions, preventing blockages and potential complications. Cleaning the tracheostomy site daily is important for hygiene but not as critical as regular suctioning. Changing the tracheostomy ties daily may not be necessary unless soiled or loose. Providing humidified oxygen may be part of the care plan but is not as directly related to maintaining the tracheostomy patency as suctioning.

5. A nurse is preparing to assess a 2-week-old newborn. Which of the following actions should the nurse plan to take?

• A. Obtain the newborn's body temperature using a tympanic thermometer
• B. Pull the pinna of the infant's ear forward before inserting the probe
• C. Auscultate the newborn's apical pulse for 60 seconds
• D. Measure the newborn's head circumference over the eyebrows and below the occipital prominence

Correct answer: C

Rationale: The correct answer is C: Auscultate the newborn's apical pulse for 60 seconds. When assessing a newborn, it is essential to auscultate the apical pulse for a full 60 seconds to accurately determine their heart rate. This method allows for a more precise measurement, considering the variability in heart rates in newborns. Choice A is incorrect because tympanic thermometers are not typically used for newborns due to their ear canals being small and not fully developed. Choice B is incorrect as pulling the pinna forward is not necessary for assessing the apical pulse. Choice D is incorrect as measuring head circumference involves a different assessment and is not relevant to determining the heart rate of a newborn.
