A client taking diltiazem, a calcium channel blocker, for hypertension has come to the clinic for a follow-up appointment. The nurse will assess the client for which adverse effects?
Chest pain and pale skin
Shortness of breath and wheezing
Peripheral edema and bradycardia
Tachycardia and anxiety
The Correct Answer is C
A. Chest pain and pale skin are not typical adverse effects associated with diltiazem use.
B. Shortness of breath and wheezing may occur due to other conditions or medications but are not common adverse effects of diltiazem.
C. Calcium channel blockers like diltiazem can cause peripheral edema due to vasodilation and bradycardia as a result of their action on the heart rate. Monitoring for these effects is essential in patients taking diltiazem.
D. Tachycardia is not an expected adverse effect of diltiazem; in fact, it is used to manage conditions where tachycardia may be present. Anxiety is also not a direct adverse effect of this medication.

Correct Answer is C
Explanation
A. An increased risk for CNS depression is not typically associated with opioid agonist-antagonists; instead, these medications may produce a ceiling effect on sedation compared to full agonists.
B. Respiratory depression is more commonly associated with full opioid agonists rather than agonist-antagonists. Agonist-antagonists can sometimes counteract respiratory depression caused by full agonists.
C. Opioid withdrawal symptoms can occur when a client who is dependent on full agonist opioids is given an agonist-antagonist, as these medications can displace the agonist from receptors, leading to withdrawal.
D. Hypotension is a possible side effect of opioids but is not a specific concern with the use of agonist-antagonists in the context of opioid therapy.
Correct Answer is B
Explanation
A. Milk does not enhance the absorption of tetracycline; rather, it contains calcium, which can bind to the antibiotic and reduce its absorption.
B. Avoiding milk and dairy products while taking tetracycline is essential as they reduce the medication's effectiveness by forming insoluble complexes with the drug.
C. Taking milk with tetracycline is not safe due to the risk of decreased absorption; simply increasing water intake does not negate this interaction.
D. While spacing the intake of milk and tetracycline might seem beneficial, it is best to avoid dairy entirely during the treatment to ensure maximum efficacy of the medication.
