Question 1 of 5
Low molecular weight heparin (LMWH) prophylaxis to prevent deep vein thrombosis/pulmonary embolism in major surgery:
Correct Answer: c
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A client is admitted to an emergency department experiencing memory deficits and decreased motor function. What alteration in brain chemistry should a nurse correlate with the production of these symptoms?
Correct Answer: D
Rationale: The correct answer is D: Decreased levels of acetylcholine. Acetylcholine is essential for memory and motor function. Reduced levels can lead to memory deficits and decreased motor function. Abnormal levels of serotonin (A), decreased levels of dopamine (B), and increased levels of norepinephrine (C) are not directly linked to memory deficits and motor function impairment.
Question 3 of 5
Which medical diagnosis and treatment should a nurse anticipate when planning care for this client?
Correct Answer: A
Rationale: The correct answer is A. Neuroleptic malignant syndrome (NMS) is a rare but potentially life-threatening side effect of antipsychotic medications like Thorazine. The treatment involves discontinuing the causative agent (Thorazine) and administering dantrolene to manage muscle rigidity and hyperthermia. Increasing Thorazine dosage (B) would worsen NMS symptoms. Treating dystonia with trihexyphenidyl (C) or bromocriptine (D) is not appropriate for NMS.
Question 4 of 5
Lithium is prescribed for a new patient. Which information from the patient’s history indicates that monitoring of serum concentrations of the drug will be challenging and critical?
Correct Answer: D
Rationale: The correct answer is D: Heart failure. Patients with heart failure often have fluid and electrolyte imbalances, affecting lithium levels. Monitoring serum lithium concentrations is critical in these patients due to the risk of toxicity. Arthritis (choice A), epilepsy (choice B), and psoriasis (choice C) do not directly impact lithium levels or require close monitoring like heart failure does.
Question 5 of 5
The nurse is administering a beta blocker to a patient. Which is the most important assessment to perform before administration?
Correct Answer: B
Rationale: The correct answer is B: Apical pulse. Before administering a beta blocker, it is crucial to assess the patient's apical pulse to monitor for potential bradycardia, a common side effect of beta blockers. This assessment helps determine if the patient's heart rate is within the safe range for administering the medication. Monitoring urine output (A) is important for assessing renal function but not specifically related to beta blocker administration. Potassium level (C) and serum level of medication (D) are also important assessments, but the most critical assessment before giving a beta blocker is to evaluate the patient's heart rate to prevent adverse effects.
