Nursing Elites

1. A client is prescribed warfarin for anticoagulation. Which of the following laboratory values should the nurse monitor?

• A. PT and INR
• B. Blood glucose levels
• C. Complete blood count (CBC)
• D. Platelet count

Correct answer: A

Rationale: The correct answer is A: PT and INR. Warfarin is an anticoagulant that affects the clotting mechanism by inhibiting vitamin K-dependent clotting factors. The PT (Prothrombin Time) and INR (International Normalized Ratio) are specific laboratory values used to monitor the effectiveness and safety of warfarin therapy. These values help healthcare providers adjust the warfarin dosage to maintain the desired level of anticoagulation. Choices B, C, and D are incorrect because blood glucose levels, complete blood count (CBC), and platelet count are not directly monitored to assess the effects of warfarin therapy.

2. When educating a client about valproic acid, which instruction is essential?

• A. Monitor for rash
• B. Expect weight loss
• C. Consider it safe during pregnancy
• D. Purchase it over-the-counter

Correct answer: A

Rationale: The correct answer is to instruct the client to monitor for rash. Valproic acid can lead to severe skin rashes, and patients must be vigilant to report any rash promptly. Choice B is incorrect as valproic acid is more likely to cause weight gain. Choice C is incorrect because valproic acid is associated with birth defects and should be avoided during pregnancy. Choice D is incorrect as valproic acid is a prescription medication and not available over-the-counter.

3. A nurse is assessing a client who is 12 hours post-surgery. The client has an indwelling urinary catheter, and the nurse notes a urinary output of 15 mL/hr. Which of the following interventions should the nurse implement first?

• A. Irrigate the catheter
• B. Assess the patency of the catheter
• C. Increase the IV fluid rate
• D. Notify the provider

Correct answer: B

Rationale: The nurse should first assess the patency of the catheter to ensure that the low output is not caused by a blockage. It is crucial to rule out any obstructions before considering other interventions. Irrigating the catheter without verifying patency may worsen the situation if there is a blockage. Increasing IV fluid rate may not address the underlying issue if the problem lies with the catheter. Notifying the provider should come after ensuring the catheter's patency.

4. A nurse is caring for a newborn immediately following birth. What should the nurse do first?

• A. Instill erythromycin ophthalmic ointment
• B. Place identification bracelets on the newborn
• C. Weigh the newborn
• D. Dry the newborn

Correct answer: D

Rationale: Drying the newborn is the first priority to prevent heat loss, which can occur rapidly in newborns due to their large surface area and lack of body fat. This helps maintain the newborn's body temperature and prevent hypothermia. Instilling erythromycin ophthalmic ointment, placing identification bracelets, and weighing the newborn can be important steps but should come after ensuring the newborn is dried to maintain their body temperature.

5. A nurse is teaching a client about the use of a metered-dose inhaler (MDI). Which instruction should the nurse include in the teaching?

• A. Inhale the medication deeply for 3-5 seconds
• B. Exhale forcefully before inhaling
• C. Shake the MDI vigorously before use
• D. Hold the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth

Correct answer: A

Rationale: Corrected Rationale: Inhaling the medication deeply for 3-5 seconds and holding the breath for 10 seconds after inhalation ensures effective medication delivery to the lungs. Choice A is the correct instruction for the use of a metered-dose inhaler (MDI). Choice B, exhaling forcefully before inhaling, is incorrect as it can lead to decreased medication delivery. Choice C, shaking the MDI vigorously before use, is also incorrect as excessive shaking can cause the medication to clump. Choice D, holding the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth, is not recommended as it may lead to improper inhalation technique.
