Question 1 of 5
The diagnostic triad of morphine overdose consists of:
Correct Answer: D
Rationale: The diagnostic triad of morphine overdose includes coma, depressed respiration, and pinpoint pupils. Coma occurs due to the central nervous system depression caused by morphine. Depressed respiration is a common symptom of opioid overdose, leading to respiratory distress and potential respiratory failure. Pinpoint pupils, also known as miosis, are a classic sign of opioid overdose and result from the effect of morphine on the autonomic nervous system. These three symptoms together are characteristic of a morphine overdose and indicate a medical emergency that requires prompt treatment.
Question 2 of 5
The nurse administers an adrenergic blocking agent in order to prevent release of what neurotransmitter?
Correct Answer: B
Rationale: Adrenergic blocking agents prevent norepinephrine from being released from the adrenal medulla or from the nerve terminal from activating the receptor, which blocks sympathetic nervous system effects. Epinephrine, serotonin, and GABA are not associated with this process. Norepinephrine is the primary neurotransmitter targeted by these agents, as it plays a key role in the sympathetic nervous system's fight-or-flight response.
Question 3 of 5
A patient is receiving 10 mEq of potassium chloride in 100 mL of normal saline intravenously (IV) to infuse over 1 hour via infusion pump. The patient has a 22-gauge peripheral IV in his right forearm and reports pain at the insertion site; the nurse notes that the site is reddened, warm, and tender to the touch. Which action would the nurse take?
Correct Answer: C
Rationale: The patient's symptoms of pain, redness, warmth, and tenderness at the IV site indicate possible infiltration or phlebitis, which can lead to tissue damage or infection. The nurse should stop the infusion and discontinue the IV immediately to prevent further complications. Aspirating and slowing the rate (A) is inappropriate in this situation. Inserting a central line (B) is not the immediate priority. Applying warm compresses (D) may be done after discontinuing the IV, but it is not the first action.
Question 4 of 5
When the nurse is reviewing a list of medications taken by an 88-year-old patient, the patient says, 'I get dizzy when I stand up.' She also states that she has nearly fainted 'a time or two' in the afternoons. Her systolic blood pressure drops 15 points when she stands up. Which type of medication may be responsible for these effects?
Correct Answer: D
Rationale: Orthostatic hypotension, characterized by dizziness and a drop in blood pressure upon standing, is a common side effect of antihypertensive medications. These medications lower blood pressure, which can lead to reduced cerebral perfusion and dizziness when the patient changes positions. NSAIDs, cardiac glycosides, and anticoagulants are less likely to cause orthostatic hypotension. Therefore, the nurse should consider antihypertensive medications as the most likely cause of the patient's symptoms and assess the need for dosage adjustments or alternative treatments.
Question 5 of 5
Dr. Rodriguez orders 250 milliliters of packed red blood cells (RBC) for a patient. This therapy is administered for the treatment of:
Correct Answer: C
Rationale: Packed red blood cells (RBCs) are used to treat anemia, a condition characterized by a low red blood cell count or hemoglobin level. Anemia can result from blood loss, chronic disease, or nutritional deficiencies. Thrombocytopenia and leukopenia involve low platelet and white blood cell counts, respectively, and are not treated with RBC transfusions. Hypoalbuminemia involves low albumin levels and requires albumin infusions, not RBCs. Therefore, anemia is the correct indication for this therapy.
