Question 1 of 5
A patient diagnosed with hypertension has been prescribed captopril. Which information is most important to teach the patient about this drug?
Correct Answer: C
Rationale: The angiotensin-converting enzyme(ACE) inhibitors frequently cause orthostatic hypotension, and patients should be taught to change position slowly to allow the vascular system time to compensate for the position change. Increasing fluid intake may counteract the effect of the medication, and the patient is taught to use gum or hard candy to relieve dry mouth. The BP should be taken in the nondominant arm by newly diagnosed patients in the morning, before taking the medication, and in the evening. Because ACE inhibitors cause potassium retention, increased intake of high-potassium foods is inappropriate.
Question 2 of 5
A patient with hypertension who has just started taking atenolol(Tenormin) returns to the health clinic after 2 weeks for a follow-up visit. The blood pressure(BP) is unchanged from the previous visit. Which action should the nurse take first?
Correct Answer: B
Rationale: Because noncompliance with antihypertensive therapy is common, the nurse's initial action should be to determine whether the patient is taking the atenolol as prescribed. The other actions also may be implemented, but these would be done after assessing patient compliance with the prescribed therapy.
Question 3 of 5
The nurse is providing care for a patient with a diagnosis of hypertension. The nurse should consequently assess the patient for signs and symptoms of which other health problem?
Correct Answer: C
Rationale: Hypertension is both a sign and a risk factor for atherosclerotic heart disease. It is not associated with structural cardiac defects, low platelet levels, or migraines.
Question 4 of 5
Regarding jugular pressure waves:
Correct Answer: B
Rationale: Atrial premature beats can cause an exaggerated 'A' wave in the jugular pulse due to increased atrial contraction against a closed or partially closed tricuspid valve.
Question 5 of 5
Foetal circulation, which is TRUE?
Correct Answer: C
Rationale: Blood in the umbilical veins is highly oxygenated, being approximately 80% saturated with O2.
