Nursing Elites

1. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and is experiencing muscle weakness. The nurse should anticipate a prescription for which of the following medications?

• A. Neostigmine
• B. Naloxone
• C. Dantrolene
• D. Vecuronium

Correct answer: A

Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers by increasing acetylcholine levels at the neuromuscular junction, thereby helping to restore muscle strength. Naloxone is an opioid antagonist used to reverse opioid effects, not neuromuscular blockade. Dantrolene is a skeletal muscle relaxant used to treat malignant hyperthermia or neuroleptic malignant syndrome, not to reverse neuromuscular blockade. Vecuronium is a nondepolarizing neuromuscular blocking agent, like the one the client received, and is not used to reverse its effects.

2. When teaching a client with a new prescription for Timolol how to insert eye drops, which instruction should the nurse include?

• A. Press your finger on the inside corner of your eye for 1 minute after application.
• B. Apply the eye drops directly on the cornea.
• C. Drop the prescribed amount of medication into the center of the conjunctival sac.
• D. Wipe your eyes gently with a tissue immediately after application.

Correct answer: C

Rationale: The correct way to administer eye drops is by instructing the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps in proper distribution and absorption of the medication. Choice A is incorrect as pressing the inside corner of the eye is not necessary. Choice B is incorrect because applying eye drops directly on the cornea can cause irritation and discomfort. Choice D is incorrect as wiping the eyes immediately after application can remove the medication and reduce its effectiveness.

3. What is the pharmacological action of metformin?

• A. Blocks stimulation of beta1 and beta2.
• B. Blocks vasoconstriction and aldosterone.
• C. Acts at many levels in the CNS to produce an anxiolytic effect.
• D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.

4. A nurse is caring for a client who has a new prescription for Metformin. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Avoid eating foods high in potassium.
• C. Take this medication at bedtime.
• D. Take this medication every other day.

Correct answer: A

Rationale: The correct instruction for a client prescribed Metformin is to take the medication with food. Taking Metformin with meals helps reduce gastrointestinal side effects and ensures better absorption. Choice B, to avoid foods high in potassium, is not directly related to Metformin. Choice C, taking the medication at bedtime, is not a standard instruction for Metformin. Choice D, taking the medication every other day, is incorrect as Metformin is typically taken daily as prescribed.

5. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

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

Correct answer: B

Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.
