ANSWERS | LATEST UPDATED VERSION
1. Discuss why beta-blockers may pose risks when used in older adult patients
for hypertension management.
Beta-blockers are preferred over other antihypertensives in older
adults.
Beta-blockers are always safe for older adults as they lower blood
pressure effectively.
Beta-blockers have no significant side effects in older adults.
Beta-blockers can cause bradycardia and hypotension, which are
more pronounced in older adults due to age-related physiological
changes.
2. If a patient with COPD is experiencing allergic rhinitis symptoms, which
additional medication might be prescribed alongside theophylline to manage
these symptoms effectively?
A bronchodilator
An antihistamine
A corticosteroid
A beta-blocker
3. Describe how calcium channel blockers contribute to the management of
stable angina.
Calcium channel blockers primarily increase blood pressure, which
helps in angina management.
Calcium channel blockers only affect the lungs and have no role in
angina.
, Calcium channel blockers increase heart rate, which is beneficial for
angina.
Calcium channel blockers help manage stable angina by decreasing
the force of heart contractions and relaxing blood vessels, which
lowers the heart's oxygen demand.
4. How will these drug interactions affect this patient?
An elderly patient with a history of asthma and hypertension presents
to the emergency department complaining of chest pain and
shortness of breath. The advanced practice registered nurse (APRN)
reviews the patient's current medications and notes that the patient is
taking propranolol and inhaled albuterol.
Albuterol can decrease propranolol's therapeutic effect.
Propranolol can decrease albuterol's therapeutic effect.
Propranolol can increase albuterol's therapeutic effect.
Albuterol can increase propranolol's therapeutic effect.
5. The patient has been prescribed enalapril for hypertension. The patient asks
the nurse how the medication lowers blood pressure. The nurse understands
that ACE inhibitors lower blood pressure through.
Vasodilation.
Sodium/water excretion.
Vasodilation and sodium/water excretion.
Decreased heart rate.
6. Describe how spironolactone's action on aldosterone receptors contributes
to heart failure management.
, Spironolactone blocks aldosterone receptors, reducing fluid
retention and cardiac workload.
Spironolactone increases sodium reabsorption, leading to decreased
blood volume.
Spironolactone enhances calcium absorption, improving heart
contractility.
Spironolactone promotes vasoconstriction, increasing blood pressure.
7. If the patient's blood pressure remains stable at 130/90 mm Hg, what might
be a reasonable next step for the healthcare team regarding the patient's
medications?
Consider tapering the thiazide diuretic if no side effects are present.
Increase the dosage of the ACE inhibitor.
Switch the patient to a different class of antihypertensive medication.
Add a beta-blocker to the current regimen.
8. What is a common side effect of both gentamicin and furosemide that should
be monitored?
Ototoxicity
Nausea
Fatigue
Headache
9. What is the primary use of spironolactone in patients with heart failure?
To increase blood pressure
To relieve COPD symptoms
, To help reduce fluid retention and improve heart function
To treat asthma symptoms
10. The nurse should consult with the HCP before administering the initial dose
of propranolol when the patient reveals a history of
peptic ulcer disease
daily alcohol use
myocardial infarction
reactive airway disease
11. Why is it important for patients taking gentamicin and furosemide to be
aware of ototoxicity?
Ototoxicity is a mild side effect that does not require monitoring.
Ototoxicity can lead to hearing loss, which is a serious side effect of
these medications.
Ototoxicity is unrelated to the effectiveness of the medications.
Ototoxicity only occurs with gentamicin, not furosemide.
12. What are common symptoms of heart failure that a patient might present
with?
Dyspnea, fatigue, peripheral edema, and distention of the jugular
veins
Headache and dizziness
Chest pain and shortness of breath
Nausea and vomiting
