1. When caring for a client prescribed Digoxin, which finding should the nurse monitor to assess for potential toxicity?
- A. Bradycardia
- B. Hypertension
- C. Hypoglycemia
- D. Hypercalcemia
Correct answer: A
Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin, a cardiac glycoside, can lead to toxic effects such as bradycardia, which is a slow heart rate. Therefore, the nurse should closely monitor the client's heart rate for any significant decreases, as this could indicate Digoxin toxicity and prompt further intervention. Choices B, C, and D are incorrect because Digoxin toxicity typically presents with bradycardia, not hypertension, hypoglycemia, or hypercalcemia.
2. A client is being educated by a healthcare provider about Terbutaline. Which of the following statements by the client indicates understanding of the teaching?
- A. This medication will stop my contractions.
- B. This medication will prevent vaginal bleeding.
- C. This medication will promote blood flow to my baby.
- D. This medication will increase my prostaglandin production.
Correct answer: A
Rationale: The correct answer is A. Terbutaline works by blocking beta2-adrenergic receptors, leading to uterine smooth muscle relaxation and stopping contractions. It is commonly used to delay preterm labor. Choice B is incorrect because Terbutaline is not used to prevent vaginal bleeding. Choice C is incorrect because Terbutaline's primary action is not related to promoting blood flow to the baby. Choice D is incorrect because Terbutaline does not increase prostaglandin production; instead, it works by blocking beta2-adrenergic receptors.
3. A healthcare professional reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the professional take?
- A. Obtain a blood specimen immediately prior to administering the next dose of medication.
- B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
- C. Ask the client to provide a urine specimen after the next dose of medication.
- D. Administer the medication, and obtain a blood specimen 30 minutes later.
Correct answer: A
Rationale: To verify trough levels of a medication, the healthcare professional should obtain a blood specimen immediately before administering the next dose of medication. This timing ensures an accurate representation of the medication's lowest concentration in the bloodstream, which is crucial for therapeutic monitoring and dose adjustments. Choice B is incorrect because waiting 24 hours after taking the medication would not provide an accurate trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect because obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level, as it is the lowest concentration before the next dose.
4. Which of the following is the antidote for Heparin toxicity?
- A. Protamine
- B. Methylene blue
- C. N-acetylcysteine
- D. Glucagon
Correct answer: A
Rationale: Protamine is the specific antidote for Heparin toxicity. Heparin is an anticoagulant medication, and if an overdose occurs or if there is excessive bleeding due to Heparin use, protamine, a positively charged molecule, can neutralize the anticoagulant effects of Heparin by forming a complex with it. This binding prevents Heparin from further inhibiting coagulation factors and helps in reversing its effects.
5. A healthcare professional is reviewing the laboratory results of a client who is taking Lithium for Bipolar Disorder. Which of the following findings should the healthcare professional report to the provider immediately?
- A. Lithium level of 1.0 mEq/L
- B. Potassium level of 3.5 mEq/L
- C. Sodium level of 140 mEq/L
- D. Creatinine level of 1.0 mg/dL
Correct answer: D
Rationale: A creatinine level of 1.0 mg/dL should be reported to the provider immediately. While a lithium level of 1.0 mEq/L falls within the therapeutic range, a creatinine level of 1.0 mg/dL could suggest early signs of kidney dysfunction, especially concerning in a client on long-term lithium therapy. It is crucial to monitor kidney function closely because lithium can be nephrotoxic over time. Elevated creatinine levels may indicate impaired kidney function and should prompt immediate reporting to the healthcare provider. Potassium and sodium levels within normal range are not immediate concerns when compared to potential kidney issues.
