Question 1 of 5
The older adult client has gastrointestinal bleeding. The client says to the nurse, 'I don't understand this. All I did was take ibuprofen (Advil) for my arthritis.' Which plan would be best as it relates to the nurse's education of this client?
Correct Answer: B
Rationale: Ibuprofen, an NSAID, can cause gastrointestinal bleeding by irritating the stomach lining, a risk higher in older adults. Substituting acetaminophen, which lacks this effect, reduces harm while managing pain, making it the best education plan. Topical drugs may not address systemic arthritis. Physician approval is wise but less specific than substitution. Pros/cons of ibuprofen inform but don't directly mitigate risk. Acetaminophen offers a safer alternative, directly addressing the bleeding issue.
Question 2 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: TPN tubing should be changed every 24 hours to prevent infection and maintain sterility. Longer intervals (B, C, D) increase the risk of bacterial contamination and sepsis.
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
The nurse should teach a patient to take their own pulse with which medication? (Hint: if pulse is <60 or >100, the patient should contact their health care provider before taking the medication)
Correct Answer: A
Rationale: Digoxin is a medication commonly prescribed to patients with heart conditions, such as heart failure and certain types of irregular heartbeats. It primarily works by slowing down the heart rate and increasing the strength of the heart's contractions. This is why patients taking digoxin are typically taught to monitor their own pulse regularly to ensure it stays within a safe range.
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.
