The WGU D116 Unit 5 Pharmacology Study Guide (2025/2026) covers essential clinical applications of medication reconciliation, antihypertensive pharmacology, and safe prescribing practices, with 100% verified answers for exam preparation. It explains the importance of accurate medication reconciliation, emphasizing the process of obtaining a complete and verified medication list—especially in emergencies when patients are unable to provide history. For instance, when a patient arrives unconscious, the provider should contact the pharmacy directly to obtain the medication list, ensuring safe continuation or adjustment of therapy. The guide clarifies that while The Joint Commission recognizes medication reconciliation as a national patient safety goal, institutions are not required to use a specific standardized protocol, though following established guidelines improves safety and reduces hospital readmissions. Additionally, the content details the pharmacological mechanisms of drugs used in hypertension management, connecting physiological effects with medication classes. It distinguishes ACE inhibitors (e.g., captopril, lisinopril), which reduce peripheral resistance and blood volume by inhibiting angiotensin II formation—but may cause a dry cough due to bradykinin accumulation. Thiazide diuretics are identified as agents that lower blood pressure primarily by decreasing blood volume through sodium and water excretion, leading to increased urination. Angiotensin II receptor blockers (ARBs), such as losartan, are shown to reduce both blood volume and vascular resistance by blocking angiotensin II binding, offering an alternative to ACE inhibitors without the cough. For pregnant patients, ACE inhibitors and ARBs are contraindicated due to fetal toxicity, requiring the prescriber to recommend safe alternatives such as labetalol or methyldopa for hypertension management during pregnancy.

CORRECT VERIFIED SOLUTIONS 100%
GUARANTEED PASS (LATEST UPDATE)

worker has accompanied the patient but does not know anything about her
medications, just which pharmacy the patient goes to.
What is the most appropriate step to take in the medication reconciliation
process at this point? - ANS ✓Call the pharmacy to obtain a medication list


What is the relationship between medication reconciliation and hospital
readmissions? - ANS ✓Medication reconciliation in combination with other
services may positively impact hospital readmissions in some institutions


True or False
Medication reconciliation must be performed using a protocol approved by
The Joint Commission. - ANS ✓False


Joint commissions has recognized medication reconciliation as a national
patient safety goal, and they have developed elects of performance for
medication reconciliation. Guidelines are made but using those measures is
not required to perform medication reconciliation


A patient who has recently started pharmacological intervention for HTN is
experiencing the physiological effects depicted on the mannequin:
decreased peripheral resistance and blood volume. This patient has most
likely been taking? - ANS ✓ACE inhibitors


Work within the RASS to inhibit angiotensin 2 from being made which
reduces peripheral resistance and blood volume

Leave bradykinin to build up in lungs which causes s/s of dry cough


A pt who has recently started pharmacological intervention for HTN is
experiencing the physiological effects depicted on the mannequin:
decreased blood volume. This patient is most likely been taking? - ANS
✓Thiazide diuretics


Work within the structures of the kidneys to decrease sodium and water
reabsorption into the blood which reduces blood volume. As a result there
is an increase in urination


A patient who has recently started pharmacological intervention for HTN is
experiencing the physiological effects depicted on the mannequin:
Decreased blood volume and peripheral resistance. This patient has most
likely been taking? - ANS ✓Angiotensin 2 receptor blockers Abs


Reduce the effects of angiotensin 2 by preventing it from binding to
receptors which decreases peripheral resistance and blood volume


An advanced practice registered nurse (APRN) is seeing a 36-year-old
female for the first time who has a history of asthma and hypertension and
is currently on an albuterol inhaler and an ACE inhibitor (captopril). At the
visit, the woman has a positive pregnancy test.
Which recommendation should the APRN make for this patient? - ANS
✓Stop captopril and replace it with another antihypertensive medication


ACE inhibitors can cause serious fetal harm-must not be given during
pregnancy


A patient with a history of diabetes, diabetic nephropathy, and
hypertension complains of numbness and loss of sensation in the lower
extremities. An advanced practice registered nurse prescribes captopril 25
mg two times a day.
