1. Which lab value should be monitored in patients receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.

2. A nurse is caring for a client who has heart failure and is receiving furosemide. Which of the following findings should the nurse identify as a therapeutic effect of the medication?

• A. Increased shortness of breath.
• B. Weight gain of 2.3 kg (5 lb).
• C. Clear lung sounds.
• D. Bounding pulse.

Correct answer: C

Rationale: The correct answer is C: Clear lung sounds. Clear lung sounds indicate a therapeutic effect of furosemide, as the medication helps reduce fluid overload in heart failure. Choice A, increased shortness of breath, is incorrect as furosemide is used to relieve symptoms like shortness of breath. Choice B, weight gain of 2.3 kg (5 lb), is incorrect as furosemide is a diuretic that helps reduce fluid retention leading to weight loss. Choice D, bounding pulse, is incorrect as furosemide does not directly impact the pulse rate.

3. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

4. A client has a new prescription for levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication in the evening before bed.
• B. Take this medication on an empty stomach.
• C. Take this medication with a full glass of milk.
• D. Take this medication with an antacid if you experience indigestion.

Correct answer: B

Rationale: The correct instruction when taking levothyroxine is to take it on an empty stomach. This enhances absorption and ensures the medication's effectiveness. Taking it with food or other substances, such as milk or antacids, can interfere with its absorption. Therefore, choices A, C, and D are incorrect.

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.
