Nursing Elites

1. 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.

2. When teaching a client with schizophrenia strategies to cope with anticholinergic effects of Fluphenazine, which of the following should the nurse suggest to minimize anticholinergic effects?

• A. Take the medication in the morning to prevent insomnia.
• B. Chew sugarless gum to moisten the mouth.
• C. Use cooling measures to decrease fever.
• D. Take an antacid to relieve nausea.

Correct answer: B

Rationale: The correct answer is B: 'Chew sugarless gum to moisten the mouth.' Chewing sugarless gum can help alleviate dry mouth, which is a common anticholinergic effect of Fluphenazine. Dry mouth can be uncomfortable and affect the client's oral health. Options A, C, and D are incorrect because they do not directly address anticholinergic effects. Taking the medication in the morning to prevent insomnia (Option A) is unrelated to anticholinergic effects. Using cooling measures to decrease fever (Option C) is not a common anticholinergic effect of Fluphenazine. Taking an antacid to relieve nausea (Option D) does not specifically target anticholinergic effects.

3. A client with breast cancer is being taught about Tamoxifen. Which of the following adverse effects of tamoxifen should the client be informed about?

• A. Irregular heart rhythm
• B. Abnormal uterine bleeding
• C. Yellowing of the sclera or dark-colored urine
• D. Difficulty swallowing

Correct answer: B

Rationale: Abnormal uterine bleeding is a known adverse effect of tamoxifen. It is important to educate the client about this side effect as those taking tamoxifen are at an increased risk for endometrial cancer. Any abnormal uterine bleeding should be promptly reported and evaluated by healthcare providers to ensure timely management and monitoring. The other options, such as irregular heart rhythm, yellowing of the sclera or dark-colored urine, and difficulty swallowing, are not typically associated with tamoxifen use and are not commonly reported adverse effects. Therefore, they are not the priority adverse effects to inform the client about.

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

• A. Take this medication at bedtime.
• B. Take this medication with food.
• C. Take this medication on an empty stomach in the morning.
• D. Take this medication with an antacid.

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance its absorption. This timing allows for optimal absorption and effectiveness of the medication. Taking it with food, at bedtime, or with an antacid may interfere with its absorption and reduce its efficacy.

5. A client is to receive Tetracaine before a Bronchoscopy. Which of the following actions should the nurse include in the plan of care?

• A. Keep the client NPO until the pharyngeal response returns.
• B. Monitor the insertion site for a hematoma.
• C. Palpate the bladder to detect urinary retention.
• D. Maintain the client on bed rest for 12 hours following the procedure.

Correct answer: A

Rationale: The correct action for the nurse to include in the plan of care is to keep the client NPO until the pharyngeal response returns. Tetracaine can affect the gag reflex, so it is important to prevent aspiration by maintaining the client NPO until the pharyngeal response is normal, which typically takes about 1 hour. Monitoring for the return of the gag reflex is crucial to prevent complications from aspiration during the first oral intake after the procedure. Choices B, C, and D are incorrect because they are not directly related to the effects of Tetracaine or the bronchoscopy procedure.
