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 taken to the trauma unit after a motorcycle accident. It is estimated that he has lost 30% of his blood volume and he is in hypovolemic shock. The nurse anticipates a transfusion with which blood product?
Correct Answer: A
Rationale: In hypovolemic shock due to significant blood loss, the primary goal is to quickly restore the lost volume of red blood cells to improve tissue perfusion and oxygen delivery. Packed Red Blood Cells (PRBCs) are the most appropriate blood product for this situation as they contain a high concentration of red blood cells and minimal plasma, making them the most efficient way to replace lost red blood cells. Whole blood, Cryoprecipitate, and Fresh Frozen Plasma (FFP) contain other blood components which are not the immediate priority in this scenario.
Question 4 of 5
A 36-year-old woman grocery store manager with a fair complexion and blue eyes presents to her primary care physician for a routine exam. She mentions a friend of hers who is taking bimatoprost to increase the length and amount of her eyelashes and asks if you would recommend it for her. Her past medical history is significant for migraine headaches. Which of the following is a side effect you should warn her about?
Correct Answer: B
Rationale: Bimatoprost for eyelashes risks permanent iris darkening , increasing melanin, especially in light eyes. Glaucoma is its therapeutic use, not a side effect here. Stevens-Johnson , weight gain , and migraines (E) aren't linked. Darkening is a key cosmetic concern.
Question 5 of 5
Central venous access devices are beneficial in pediatric therapy because:
Correct Answer: B
Rationale: Central venous access devices are beneficial in pediatric therapy because they provide a reliable and convenient access point for administering medications, fluids, and blood products without restricting the use of a child's arms. This allows children to move freely and participate in activities while receiving necessary treatments, enhancing their comfort and quality of life.
