1. A nurse is teaching a client who has a new prescription for Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?

A. Tachycardia
B. Hypoglycemia
C. Bradycardia
D. Hypertension

Correct answer: C

Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect. The client should monitor their pulse regularly and report any significant decreases.

2. How is lithium typically administered?

A. Intravenously
B. Intramuscularly
C. Orally
D. Sublingually

Correct answer: C

Rationale: Lithium is typically administered orally to ensure proper absorption and distribution in the body. By taking lithium orally, it allows the medication to be absorbed through the gastrointestinal tract and distributed effectively. Intravenous and intramuscular routes are not commonly used for lithium administration as they can lead to rapid, unpredictable absorption and increase the risk of toxicity. Sublingual administration is also not the typical route for lithium, as it is usually taken orally for consistent and controlled absorption.

3. 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.

4. A healthcare professional in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?

A. Isosorbide
B. Phenytoin
C. Metronidazole
D. Prednisone

Correct answer: A

Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.

5. Which of the following is not related to drug toxicity of Atenolol?

A. CHF
B. Tachycardia
C. AV block
D. Sedative appearance

Correct answer: B

Rationale: Atenolol, a beta-blocker, is not typically associated with tachycardia. Instead, drug toxicity of Atenolol is more commonly linked to bradycardia due to its beta-blocking effects on the heart's electrical conduction system. Symptoms of Atenolol toxicity may include heart failure (CHF), AV block, and a sedative appearance, but not tachycardia.
