Question 1 of 5
The following are sympathomimetic amines , EXCEPT:
Correct Answer: B
Rationale: Sympathomimetic amines are compounds that mimic the effects of the sympathetic nervous system. Options A, C, D, and E (epinephrine, norepinephrine, levonordefrin, and phenylephrine) are all sympathomimetic amines commonly used in dentistry for their vasoconstrictive properties. Felypressin, on the other hand, is a synthetic vasopressin analog and does not have sympathomimetic properties. It is commonly used in dentistry as a local vasoconstrictor to prolong the anesthetic effect.
Question 2 of 5
A patient who takes high-dose aspirin to treat arthritis will need to take prednisone to treat an acute flare of symptoms. What action will the nurse perform?
Correct Answer: A
Rationale: When a patient taking high-dose aspirin for arthritis requires prednisone for an acute flare, the nurse should be aware that prednisone can increase blood glucose levels. As such, the nurse should monitor the patient for signs and symptoms of hyperglycemia, not hypoglycemia. It is essential to closely monitor the patient's blood glucose levels to prevent complications associated with high blood sugar levels, such as hyperglycemia. It is also crucial to educate the patient about the potential side effects of prednisone and instruct the patient on how to manage blood glucose levels while taking the medication.
Question 3 of 5
Before administering a nonselective adrenergic blocker, what should the nurse assess?
Correct Answer: A
Rationale: Monitor vital signs and assess cardiovascular status including pulse, blood pressure, and cardiac output to evaluate for possible cardiac effects. Although assessment of bowel sounds, appetite, serum albumin level, or serum sodium and potassium levels may be important to patient care, they are not related to administration of a nonselective adrenergic blocking agent. The nurse should prioritize cardiovascular assessments to ensure patient safety.
Question 4 of 5
Which is appropriate nursing care for a patient receiving total parenteral nutrition (TPN) in an acute care setting? (Select all that apply.)
Correct Answer: A
Rationale: Monitoring blood glucose (A) is critical because TPN can cause hyperglycemia. Measuring intake and output (B) helps assess fluid balance. Monitoring the insertion site (D) is essential to detect infection or infiltration. Blood should never be administered through the TPN line (C) due to risk of contamination.
Question 5 of 5
An adult patient has been taking a drug (Drug A) that is highly metabolized by the cytochrome p-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome p-450 system. You should monitor this patient for:
Correct Answer: C
Rationale: Drug B, as an inducer of the cytochrome p-450 system, increases the metabolism of Drug A, leading to lower plasma concentrations and reduced therapeutic effects of Drug A. This interaction is a common concern in polypharmacy, where one drug affects the metabolism of another. Monitoring for decreased efficacy of Drug A is essential to ensure the patient receives adequate treatment. Increased adverse effects of Drug B or decreased effects of Drug B are less likely in this scenario.
