Question 1 of 5
The nurse administers calcium intravenously (IV) to the client. What will a key assessment by the nurse include?
Correct Answer: B
Rationale: IV calcium risks infiltration-site assessment (e.g., swelling) ensures safety, per protocol. Glucose/potassium aren't directly tied-edema is secondary. Site check prevents complications, per administration.
Question 2 of 5
When the nurse is reviewing a list of medications taken by an 88-year-old patient, the patient says, 'I get dizzy when I stand up.' She also states that she has nearly fainted 'a time or two' in the afternoons. Her systolic blood pressure drops 15 points when she stands up. Which type of medication may be responsible for these effects?
Correct Answer: D
Rationale: Orthostatic hypotension, characterized by dizziness and a drop in blood pressure upon standing, is a common side effect of antihypertensive medications. These medications lower blood pressure, which can lead to reduced cerebral perfusion and dizziness when the patient changes positions. NSAIDs, cardiac glycosides, and anticoagulants are less likely to cause orthostatic hypotension. Therefore, the nurse should consider antihypertensive medications as the most likely cause of the patient's symptoms and assess the need for dosage adjustments or alternative treatments.
Question 3 of 5
Which statement regarding medication distribution within the body is accurate?
Correct Answer: C
Rationale: Lipid-soluble drugs distribute widely, crossing membranes like the blood-brain barrier easily, unlike water-soluble ones. The barrier blocks some, not all, drugs. High blood flow aids delivery, not hinders. Protein complexes limit free drug, not enable crossing. Lipid solubility enhances distribution, a pharmacokinetic truth.
Question 4 of 5
A patient who has recently started therapy on a statin drug asks the nurse how long it will take until he sees an effect on his serum cholesterol. Which statement would be the nurse™s best response?
Correct Answer: B
Rationale: The nurse's best response would be, "It takes 6 to 8 weeks to see a change in cholesterol levels." Statin drugs typically take around 6 to 8 weeks before a noticeable effect on serum cholesterol levels is seen. This timeframe allows the medication to fully take effect and lower the cholesterol levels in the blood. Patients should continue with the prescribed treatment regimen and have their cholesterol levels monitored regularly to assess the effectiveness of the medication.
Question 5 of 5
What is the therapeutic use of Albuterol?
Correct Answer: A
Rationale: Albuterol is a medication that belongs to the class of beta-2 adrenergic agonists, which are primarily used for bronchodilation. It works by relaxing the muscles in the airways, allowing them to widen and making breathing easier for individuals with conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. Albuterol helps to relieve symptoms of bronchospasm, such as wheezing, shortness of breath, and chest tightness. It is commonly used as a rescue inhaler for quick relief of acute bronchospasm.
