QUESTION 1
A client is prescribed lisinopril for hypertension. Which of the following is the
primary mechanism of action for this medication?
A) Blocking beta-adrenergic receptors
B) Inhibiting angiotensin-converting enzyme
C) Blocking calcium channels in the heart
D) Promoting sodium excretion in the kidneys
E) Vasodilation through direct smooth muscle relaxation
CORRECT ANSWER: B) Inhibiting angiotensin-converting enzyme
Lisinopril is an ACE inhibitor that works by blocking the conversion of angiotensin I
to angiotensin II, a potent vasoconstrictor. This results in vasodilation and
decreased blood pressure. ACE inhibitors are first-line agents for hypertension
management and are also used in heart failure and post-MI clients.
,QUESTION 2
A nurse is administering metformin to a client with type 2 diabetes. Which
assessment finding would warrant holding this medication?
A) Blood glucose level of 180 mg/dL
B) Serum creatinine of 2.5 mg/dL
C) Hemoglobin A1C of 7.5%
D) History of hypertension
E) Age greater than 65 years
CORRECT ANSWER: B) Serum creatinine of 2.5 mg/dL
Metformin is contraindicated in clients with renal impairment because it is excreted
unchanged through the kidneys. Elevated serum creatinine indicates reduced renal
function, increasing the risk of lactic acidosis, a serious and potentially fatal adverse
effect. Current guidelines recommend avoiding metformin when creatinine
clearance is less than 30 mL/min or eGFR is severely reduced.
QUESTION 3
A client taking warfarin reports consuming large amounts of leafy green
vegetables. What is the nurse's primary concern with this dietary intake?
A) Increased risk of bleeding due to vitamin K deficiency
B) Decreased anticoagulant effect due to vitamin K content
C) Increased warfarin metabolism by hepatic enzymes
D) Development of thrombophlebitis
E) Interaction with warfarin protein binding
CORRECT ANSWER: B) Decreased anticoagulant effect due to vitamin K
content
,Leafy green vegetables are rich in vitamin K, which is a cofactor for clotting factors
II, VII, IX, and X. Vitamin K antagonizes the effect of warfarin, reducing its
anticoagulant potency. Clients on warfarin should maintain consistent vitamin K
intake and INR should be monitored closely if dietary intake changes significantly.
QUESTION 4
Which of the following medications is a beta-2 agonist used for acute asthma
exacerbations?
A) Ipratropium bromide
B) Albuterol
C) Beclomethasone
D) Theophylline
E) Montelukast
CORRECT ANSWER: B) Albuterol
Albuterol is a selective beta-2 agonist that causes rapid bronchodilation by
stimulating beta-2 receptors on bronchial smooth muscle. It is the first-line
medication for acute asthma symptoms and provides rapid relief within minutes
when administered via nebulizer or inhaler. It is not effective for long-term control
and should not be used as monotherapy.
QUESTION 5
A client is prescribed amoxicillin for a bacterial infection. Which finding would
indicate a true allergy versus a common side effect?
A) Mild diarrhea occurring on the third day
B) Urticaria and angioedema occurring within 30 minutes
, C) Nausea and vomiting
D) Headache
E) Photosensitivity
CORRECT ANSWER: B) Urticaria and angioedema occurring within 30 minutes
True penicillin allergies involve immediate hypersensitivity reactions such as
urticaria, angioedema, bronchospasm, and anaphylaxis occurring within minutes to
hours. Mild diarrhea, nausea, and headache are common side effects, not allergic
reactions. Photosensitivity is not typical of amoxicillin. Documenting true IgE-
mediated reactions is critical for safe medication selection in future care.
QUESTION 6
A nurse is administering morphine to a client with severe cancer pain. Which
nursing intervention is most important to prevent a common adverse effect?
A) Monitor heart rate continuously
B) Increase fluid and fiber intake
C) Assess pupil size every hour
D) Monitor blood pressure for hypertension
E) Restrict sodium intake
CORRECT ANSWER: B) Increase fluid and fiber intake
Opioids such as morphine commonly cause constipation due to decreased GI
motility. Preventive measures should be implemented proactively, including
increased fluid intake, dietary fiber, and possibly stool softeners or laxatives.
Constipation can be severe enough to warrant discontinuation of the opioid if not
managed. This is a predictable adverse effect requiring nursing intervention.
