Question 1 of 5
Which over-the-counter (OTC) antihistamine combination contains an analgesic property?
Correct Answer: D
Rationale: Actifed Plus combines acetaminophen (an analgesic) with antihistamine and decongestant, relieving pain alongside allergy symptoms. Sudafed PE and Triaminic contain chlorpheniramine and phenylephrine, no analgesics. Tavist has clemastine alone. Choice D's analgesic property distinguishes it, relevant for nurses advising on OTC options.
Question 2 of 5
What is/are the major adverse/side effects of regular insulin? Select all that apply
Correct Answer: A
Rationale: A. Hypoglycemia is a major adverse effect of regular insulin. This occurs when insulin lowers blood glucose levels too much, causing symptoms such as sweating, shaking, confusion, and even loss of consciousness if severe.
Question 3 of 5
The nurse is reviewing new medication orders for a patient who has an epidural catheter for pain relief. One of the orders is for enoxaparin (Lovenox), a low“molecular-weight heparin (LMWH). What is the nurse™s priority action?
Correct Answer: C
Rationale: The priority action for the nurse in this situation is to contact the prescriber because the administration of LMWH (such as enoxaparin) is contraindicated in patients with epidural catheters due to the increased risk of spinal or epidural hematoma formation. Spinal or epidural hematoma can lead to serious neurologic complications, including paralysis. Therefore, it is crucial for the nurse to verify the order with the prescriber and explore alternative anticoagulant options that are safe to use in patients with epidural catheters. Giving the LMWH as ordered without addressing this contraindication could result in harm to the patient.
Question 4 of 5
A client with bipolar disorder is prescribed lithium carbonate. Which symptom should the nurse teach the client to report?
Correct Answer: C
Rationale: Lithium stabilizes mood but risks toxicity (e.g., >1.5 mEq/L), causing tremors , a neurologic sign needing reporting to adjust dosing or check levels. Thirst and weight gain are common, manageable. Nausea occurs but is less urgent unless severe. Tremors indicate potential overdose, critical in bipolar disorder where narrow therapeutic range demands vigilance, making C the key symptom to report.
Question 5 of 5
A 19-year-old man attempts suicide after failing all of his college courses. He goes home and takes more than 90 digoxin tablets (0.25 mg each), ingesting them about 3 h prior to presentation at the emergency department. He is brought to the hospital by his brother. Vital signs are as follows: pulse is 50 beats/minute, and the electrocardiogram indicates third-degree heart block. Serum electrolytes are normal. Which of the following is the most important therapy to initiate in this patient?
Correct Answer: B
Rationale: Digoxin overdose (bradycardia, heart block) requires digoxin immune Fab , binding free digoxin to reverse toxicity. Amiodarone and lidocaine treat arrhythmias but not the cause. Potassium and verapamil (E) worsen hyperkalemia or block. Fab is urgent here.
