Nursing Elites

1. A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory values should the nurse monitor?

• A. Hemoglobin
• B. aPTT
• C. INR
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: aPTT. The activated partial thromboplastin time (aPTT) is monitored to assess the therapeutic effect of heparin and to adjust the infusion rate if needed. Monitoring hemoglobin levels (choice A) is important for assessing anemia but is not specific to heparin therapy. INR (choice C) is used to monitor the effects of warfarin, not heparin. Platelet count (choice D) is important to monitor for heparin-induced thrombocytopenia, but aPTT is the primary laboratory value used to monitor heparin therapy.

2. A nurse is providing discharge teaching to a client who has a new prescription for warfarin. Which of the following client statements indicates an understanding of the teaching?

• A. I will need to have my INR checked regularly while taking this medication.
• B. I should avoid eating leafy green vegetables while taking this medication.
• C. I will stop taking this medication if I experience nausea.
• D. I will avoid taking aspirin while taking this medication.

Correct answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.

3. A nurse is caring for a client who has a new prescription for levothyroxine. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?

• A. Calcium
• B. Sodium
• C. Thyroid-stimulating hormone (TSH)
• D. Magnesium

Correct answer: C

Rationale: The correct answer is C: Thyroid-stimulating hormone (TSH). Monitoring TSH levels is crucial to assess the effectiveness of levothyroxine in clients with hypothyroidism. TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones. In hypothyroidism, where the thyroid gland is underactive, administering levothyroxine helps to normalize thyroid hormone levels. Monitoring TSH levels allows the healthcare provider to adjust the levothyroxine dosage to ensure that thyroid hormone levels are within the therapeutic range. Choices A, B, and D (Calcium, Sodium, and Magnesium) are not directly related to assessing the effectiveness of levothyroxine therapy in hypothyroidism and would not provide relevant information regarding the medication's efficacy.

4. A client who has a positive stool culture for Clostridium difficile should be placed in which type of room for infection control purposes?

• A. Wear a face shield prior to entering the room.
• B. Place the client in a private room.
• C. Place the client in a negative pressure room.
• D. Use an alcohol-based hand rub following client care.

Correct answer: B

Rationale: Placing the client in a private room is the appropriate infection control measure for C. difficile to prevent the spread of infection. While wearing a face shield may be necessary for procedures that generate splashes or sprays, it is not the primary precaution for C. difficile. Negative pressure rooms are typically used for airborne infections, not for C. difficile. Using an alcohol-based hand rub is important for hand hygiene but is not specific to managing C. difficile infection.

5. A nurse is reviewing the laboratory values of a client who is taking spironolactone. Which of the following values should the nurse report to the provider?

• A. Sodium 144 mEq/L
• B. Potassium 5.2 mEq/L
• C. Bicarbonate 24 mEq/L
• D. Magnesium 1.9 mEq/L

Correct answer: B

Rationale: The correct answer is B: 'Potassium 5.2 mEq/L.' When a client is taking spironolactone, which is a potassium-sparing diuretic, monitoring potassium levels is crucial. A potassium level of 5.2 mEq/L is higher than normal and can lead to cardiac dysrhythmias, so it should be reported. Choices A, C, and D are within normal ranges and would not be of immediate concern when assessing a client taking spironolactone.
