Question 1 of 5
Epinephrine can compromise the stability of formed blood clot because it is a:
Correct Answer: B
Rationale: Epinephrine can compromise the stability of a formed blood clot because it is a fibrinolytic agent. Fibrinolysis is the process of breaking down fibrin, the main protein component of blood clots, and promoting the dissolution of the clot. Epinephrine is a hormone that acts on adrenergic receptors, including beta-2 adrenergic receptors, which can trigger the activation of fibrinolysis pathways. By promoting fibrinolysis, epinephrine can weaken and compromise the stability of a formed blood clot, leading to potential clot breakdown and increased risk of bleeding. This mechanism is important to consider when using epinephrine in situations where clot stability is crucial, such as in patients with bleeding disorders or undergoing surgery.
Question 2 of 5
A patient is taking a cephalosporin. The nurse anticipates which appropriate nursing intervention(s) for this medication? (Select all that apply.)
Correct Answer: A
Rationale: Cephalosporins are antibiotics that can cause nephrotoxicity, particularly in patients with pre-existing renal impairment. Monitoring renal function is essential to detect any decline in kidney function early. Liver function studies are also important because cephalosporins can occasionally cause hepatotoxicity. Intravenous cephalosporins should be infused over 30 minutes to ensure proper absorption and minimize adverse effects. Mouth ulcers are not a common side effect of cephalosporins, but monitoring for superinfections, such as oral thrush, is important. Advising the patient to stop the medication when they feel better is incorrect, as it can lead to antibiotic resistance.
Question 3 of 5
In what patient is propranolol (Inderal) contraindicated?
Correct Answer: B
Rationale: Beta-adrenergic blocking agents are contraindicated in patients with bradycardia, heart failure, and heart block. The drug would not be contraindicated in the other patients. The nurse should assess the patient’s medical history and contraindications before administering propranolol to ensure safe and effective treatment.
Question 4 of 5
A patient is receiving TPN at home. The visiting nurse assists the family with the care plan, which includes changing the TPN solution and tubing. What is the recommended initial frequency for changing the tubing?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A nurse is providing instructions to a client receiving baclofen (Lioresal). Which of the following would be included in the teaching plan?
Correct Answer: D
Rationale: Baclofen is a muscle relaxant used to treat spasticity. Weakness is a potential side effect and should be reported to the physician, as it may indicate an adverse reaction or the need for dose adjustment. Limiting fluid intake is not typically recommended, and holding the medication due to diarrhea is not a standard instruction. While alcohol can enhance the sedative effects of baclofen, the primary concern is monitoring for weakness, which could impact the patient's safety and mobility.
