1. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?

A. Heparin
B. Alprazolam
C. Digoxin
D. Levothyroxine

Correct answer: C

Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.

2. Which of the following is not a known effect of the drug Clozapine?

A. Agranulocytosis
B. Antipsychotic
C. Used for Schizophrenia
D. Hyperactivity

Correct answer: D

Rationale: Clozapine is associated with side effects like agranulocytosis (a serious blood condition), sedation (not hyperactivity), and is used as an antipsychotic to treat schizophrenia. Hyperactivity is not a typical effect of Clozapine, making it the correct answer in this context.

3. When teaching a client with a new prescription for Sulfasalazine, which instruction should the nurse include?

A. Expect orange discoloration of urine and skin.
B. Increase your intake of high-sodium foods.
C. Take the medication with a full glass of milk.
D. Expect your stools to be black and tarry.

Correct answer: A

Rationale: The correct instruction to include when teaching a client with a new prescription for Sulfasalazine is to expect orange discoloration of urine and skin. Sulfasalazine can cause this harmless side effect, which does not necessitate discontinuation of the medication. It is crucial for the nurse to educate the client about this expected outcome to prevent unnecessary concern or discontinuation of the medication. Choices B, C, and D are incorrect. Increasing intake of high-sodium foods is not recommended with Sulfasalazine, as it can worsen certain side effects. Taking the medication with a full glass of milk is not necessary for Sulfasalazine administration. Expecting stools to be black and tarry is not an expected side effect of Sulfasalazine.

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

A. Avoid consuming foods high in vitamin K.
B. Monitor your blood pressure regularly.
C. Increase your intake of green, leafy vegetables.
D. Take the medication with a high-fat meal.

Correct answer: A

Rationale: The correct answer is to advise the client to avoid consuming foods high in vitamin K. Warfarin's effectiveness can be affected by vitamin K intake. Clients should maintain a consistent intake of vitamin K and avoid sudden increases in foods high in vitamin K to ensure the medication works properly and consistently. Choices B, C, and D are incorrect. Monitoring blood pressure, increasing intake of green, leafy vegetables, or taking the medication with a high-fat meal are not specific instructions related to Warfarin therapy.

5. What are the Therapeutic Effects of Lithium?

A. Prevents or decreases the incidence of acute manic episodes
B. Maintenance of blood glucose
C. Control of hyperglycemia in diabetic patients
D. Diminished seizure activity

Correct answer: A

Rationale: The therapeutic effect of lithium is that it prevents or decreases the incidence of acute manic episodes in patients with bipolar disorder. Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder due to its ability to reduce the frequency and severity of manic episodes. Choices B, C, and D are incorrect as lithium is not used for the maintenance of blood glucose, control of hyperglycemia in diabetic patients, or to diminish seizure activity. These effects are not associated with the use of lithium as a medication.
