Nursing Elites

1. A patient is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?

• A. Hemoglobin
• B. Prothrombin time (PT)
• C. Bleeding time
• D. Activated partial thromboplastin time (aPTT)

Correct answer: B

Rationale: The correct answer is to monitor Prothrombin time (PT) when a patient is on warfarin therapy. Warfarin affects blood clotting, and PT is used to assess the therapeutic effect of this medication. Hemoglobin (Choice A) is not directly affected by warfarin therapy and does not reflect its therapeutic effect. Bleeding time (Choice C) measures the time it takes for bleeding to stop after a standardized cut and is not specific to warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. 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.

3. What is the therapeutic action of Phenytoin?

• A. Antidiabetic
• B. Anticonvulsant
• C. Mood stabilizer
• D. Antianxiety agent

Correct answer: B

Rationale: Phenytoin is primarily used as an anticonvulsant to prevent and control seizures. It works by stabilizing electrical activity in the brain, making it effective in managing conditions like epilepsy. Antidiabetic medications are used to regulate blood sugar levels, mood stabilizers help manage mood disorders, and antianxiety agents are used to reduce anxiety symptoms, none of which are the primary therapeutic action of Phenytoin.

4. What symptom would alert the healthcare professional to hold Albuterol and notify a healthcare professional immediately?

• A. Insomnia
• B. Paradoxical bronchospasm
• C. Nausea
• D. Headache

Correct answer: B

Rationale: If a patient experiences paradoxical bronchospasm after taking Albuterol, the medication should be withheld, and a healthcare professional should be notified immediately. Paradoxical bronchospasm is a serious adverse reaction where the airways constrict instead of dilating, leading to breathing difficulties. This condition requires prompt medical attention to assess and manage the patient's respiratory status. The other options, insomnia, nausea, and headache, are not typically associated with the need to hold Albuterol and notify a healthcare professional immediately.

5. A client has a new prescription for Adalimumab for Rheumatoid Arthritis. Based on the route of administration of Adalimumab, which of the following should the nurse plan to monitor?

• A. The vein for thrombophlebitis during IV administration.
• B. The subcutaneous site for redness following injection.
• C. The oral mucosa for ulceration after oral administration.
• D. The skin for irritation following removal of a transdermal patch.

Correct answer: B

Rationale: Adalimumab is administered subcutaneously. Injection-site redness and swelling are common adverse effects. Therefore, the nurse should monitor the subcutaneous site for redness following the injection to assess for any potential issues or reactions.
