Question 1 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.
Question 2 of 5
When administering the medication Spironolactone, when is the best time to administer it?
Correct Answer: D
Rationale: The best time to administer Spironolactone is in the morning. This is because Spironolactone is a diuretic that can increase urination, and taking it in the morning can help prevent disrupting the sleep cycle by decreasing the need to urinate during the night. Additionally, taking Spironolactone in the morning allows for better management of any potential electrolyte imbalances that may occur as a side effect of the medication, as healthcare providers are more readily available during daytime hours.
Question 3 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 4 of 5
When teaching a patient about antihypertensive drug therapy, which statements by the nurse are correct? (Select all that apply.)
Correct Answer: A
Rationale: A. You need to have your blood pressure checked once a week and keep track of the readings. - This is correct because monitoring blood pressure regularly is essential to assess the effectiveness of antihypertensive drug therapy and make any necessary adjustments.
Question 5 of 5
A 65-year-old man with end-stage renal disease because of diabetes recently underwent a renal transplant. He has been responding well to the transplant and his creatinine has stabilized around 2.1 mg/dL. He was placed on immunosuppressive therapy with muromonab. What is the mechanism of action of muromonab?
Correct Answer: A
Rationale: Muromonab (OKT3) prevents transplant rejection by binding CD3 on T cells . This depletes and inactivates T cells. FK-binding , IL-2 receptor , mTOR , and calcineurin (E) are other drugs' mechanisms. CD3 targeting ensures immunosuppression in this patient.
