Question 1 of 5
Beta-adrenergic blocking drugs are used in children for disorders similar to those in adults. What adrenergic blocking agent is used during surgery for pheochromocytoma?
Correct Answer: C
Rationale: Phentolamine is used during surgery for pheochromocytoma in children. Prazosin is used to treat hypertension in children. Propranolol and guanethidine are not indicated for use in children with a pheochromocytoma. The nurse should understand the indications for phentolamine to ensure safe and effective administration.
Question 2 of 5
A 52-year-old man who works as an air traffic controller has seasonal allergies. Currently, he is very symptomatic but cannot miss work because of staffing issues. Which of the following agents would be best suited for this patient?
Correct Answer: D
Rationale: An air traffic controller needs a non-sedating allergy treatment. Fexofenadine , a second-generation antihistamine, avoids drowsiness. Chlorpheniramine , Diphenhydramine , and Doxylamine sedate. Hydroxylamine (E) isn't a drug. Fexofenadine ensures safety and efficacy for his job.
Question 3 of 5
What decreases the renin angiotensin aldosterone system?
Correct Answer: A
Rationale: Angiotensin 2 receptor antagonists work by blocking the action of angiotensin 2 on its receptors, therefore inhibiting the renin-angiotensin-aldosterone system (RAAS). By inhibiting this system, angiotensin 2 receptor antagonists help to decrease blood pressure and reduce the workload on the heart. This is in contrast to ACE inhibitors, which also affect the RAAS but work by preventing the formation of angiotensin 2 in the first place. Beta blockers, such as propranolol, work by blocking the effects of adrenaline (epinephrine) on beta receptors, mainly in the heart. While they are commonly used to manage high blood pressure and reduce the heart rate, they do not directly decrease the renin-angiotensin-aldosterone system like angiotensin 2 receptor antagonists.
Question 4 of 5
During diuretic therapy, the nurse monitors the fluid and electrolyte status of the patient. Which assessment findings are symptoms of hyponatremia? (Select all that apply.)
Correct Answer: B
Rationale: Lethargy is a common symptom of hyponatremia, which is a low sodium level in the blood. it is often associated with a decrease in brain function due to the imbalance of electrolytes.
Question 5 of 5
Which symptoms experienced over 1 month would be most helpful to diagnose bipolar disorder?
Correct Answer: D
Rationale: Bipolar disorder's mania includes increased goal-directed activity, talkativeness, and distractibility-per DSM-5-over a month with depression cycles. Sleep/death/hallucinations lean psychotic. Delusions/fatigue suggest schizophrenia or depression. Eating/despair/ideas mix symptoms. Manic traits diagnose, per criteria.
