Question 1 of 5
Why is it important to monitor ins and outs with patients using ACE inhibitors?
Correct Answer: A
Rationale: ACE inhibitors are known to cause a decrease in blood pressure as part of their mechanism of action. Monitoring the patient's blood pressure regularly while on ACE inhibitors is crucial to identify any significant drops that may lead to hypotension. This proactive monitoring allows healthcare providers to adjust the dosage of the medication or provide necessary interventions to prevent adverse effects such as dizziness, syncope, or compromised tissue perfusion. Monitoring ins and outs with patients using ACE inhibitors primarily focuses on assessing for potential decreased blood pressure as a key safety measure during treatment.
Question 2 of 5
A patient asks the nurse to tell her more about a new drug the patient has been prescribed called
Correct Answer: C
Rationale: The response, "This drug is the first medication your health care provider will use to treat your angina," is accurate because Ranexa (ranolazine) is commonly used as a first-line treatment for chronic angina. It is typically prescribed when other angina medications, such as beta-blockers or calcium channel blockers, are not sufficient or well-tolerated by the patient. Ranexa works by helping the heart muscle to relax, which can improve blood flow to the heart and reduce angina symptoms. It is important for the patient to understand that Ranexa is specifically intended to treat angina and should not be used for other conditions without consulting their healthcare provider.
Question 3 of 5
The nurse administering the phosphodiesterase inhibitor milrinone (Primacor) recognizes that this drug will have a positive inotropic effect. Which result reflects this effect?
Correct Answer: C
Rationale: Milrinone (Primacor) is a phosphodiesterase inhibitor that acts by increasing the levels of cyclic adenosine monophosphate (cAMP) in cardiac muscle cells. This leads to an increased force of cardiac contractions, which is known as a positive inotropic effect. This effect results in the heart muscle contracting more forcefully, leading to an increased cardiac output. The other options (A. Increased heart rate, B. Increased blood vessel dilation, D. Increased conduction of electrical impulses across the heart) do not directly relate to the inotropic effect of milrinone.
Question 4 of 5
A patient with a history of malaria who is being treated with chloroquine is in the clinic for a follow-up visit. What should the nurse advise the patient to do?
Correct Answer: A
Rationale: Chloroquine can cause retinopathy, so patients should be advised to report any visual changes promptly. Taking the medication with milk is not necessary. Sunlight avoidance is not specifically required for chloroquine, though it may cause photosensitivity in some patients. Increasing fluid intake is not a specific recommendation for chloroquine use.
Question 5 of 5
Which pain theory is based on the existence of a specific pain system?
Correct Answer: D
Rationale: The specificity theory of pain proposes that there is a specific pain system in the body that is responsible for detecting and transmitting pain signals. According to this theory, specific pain receptors exist that are sensitive only to pain stimuli and are separate from other sensory receptors for touch, temperature, or pressure. When tissue damage or injury occurs, these pain receptors are activated, and they send signals through specific pain pathways to the brain, resulting in the sensation of pain. The specificity theory suggests that pain is a distinct sensory modality with its own dedicated system, separate from other sensory modalities.
