Cardiovascular Drug Therapy Questions
Question 1 of 5
Which of the following symptoms should a nurse associate with the development of decreased levels of thyroid-stimulating hormone (TSH) in a newly admitted client? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Depression. Decreased TSH levels are associated with hyperthyroidism, which can lead to symptoms like depression due to the impact on neurotransmitters. Fatigue may be seen in hypothyroidism with increased TSH levels. Increased libido is more commonly associated with hyperthyroidism. Mania is not typically linked to thyroid disorders.
Question 2 of 5
A depressed patient is receiving imipramine (Tofranil) 300 mg daily. Which side effect requires seeking medical attention?
Correct Answer: D
Rationale: The correct answer is D: Urinary retention. Imipramine is a tricyclic antidepressant that can cause anticholinergic side effects like urinary retention. This is a serious condition that requires immediate medical attention to prevent complications such as urinary tract infection or bladder damage. Dry mouth (A), blurred vision (B), and nasal congestion (C) are common side effects of imipramine that are usually mild and do not necessitate immediate medical attention.
Question 3 of 5
A patient is placed on heparin, and the nurse acknowledges that heparin is effective for preventing clot formation in patients who have which disorder(s)? (Select the one tha does not apply.)
Correct Answer: C
Rationale: Rationale: Heparin is effective for preventing clot formation in disorders involving arterial or venous thrombosis, such as coronary thrombosis and deep vein thrombosis. However, heparin is contraindicated in hemorrhagic stroke due to the risk of increasing bleeding. Heparin can worsen bleeding in disseminated intravascular coagulation. Therefore, the correct answer is C.
Question 4 of 5
A nurse can anticipate anticholinergic side effects are likely when a patient takes:
Correct Answer: D
Rationale: The correct answer is D, fluphenazine (Prolixin). Fluphenazine is a typical antipsychotic that exerts its effects by blocking dopamine receptors in the brain, causing anticholinergic side effects such as dry mouth, constipation, blurred vision, and urinary retention. The other options (A, B, C) are not typically associated with significant anticholinergic side effects. Lithium is known for renal and thyroid side effects, buspirone for dizziness and nausea, and risperidone for metabolic side effects. Therefore, D is the correct choice for anticipating anticholinergic side effects in patients.
Question 5 of 5
Which neurotransmitter is involved in the movement disorders seen in Parkinson disease and in the deficits seen in schizophrenia and other psychoses?
Correct Answer: A
Rationale: The correct answer is A: Dopamine. In Parkinson's disease, there is a decrease in dopamine levels leading to movement disorders. In schizophrenia, there is an imbalance in dopamine transmission contributing to the cognitive deficits and positive symptoms. Melatonin (B) is involved in sleep regulation. Serotonin (C) is associated with mood regulation. Norepinephrine (D) plays a role in the sympathetic nervous system.
