A 78-year-old patient is in the recovery room after having a lengthy surgery on his hip. As he is gradually awakening, he requests pain medication. Within 10 minutes after receiving a dose of morphine sulfate, he is very lethargic and his respirations are shallow, with a rate of 7 breaths/minute. The nurse prepares for which priority action at this time?

Assessment of the patient's pain level

Close observation of signs of opioid tolerance

Immediate intubation and artificial ventilation

Administration of naloxone

Answer and Explanation

The Correct Answer is D

A.   Assessment of the patient's pain level: While pain assessment is important, the patient's lethargy and shallow respirations indicate a potential opioid overdose, which takes priority.
B.   Close observation of signs of opioid tolerance: The patient's symptoms are indicative of opioid overdose, not tolerance.
C.   Immediate intubation and artificial ventilation: While respiratory support may eventually be necessary if the patient's condition deteriorates further, administering naloxone to reverse the opioid effects is the initial priority.
D.   Administration of naloxone: Naloxone is an opioid antagonist used to reverse opioid overdose by blocking opioid receptors, which can rapidly restore normal respiratory function and
consciousness in patients experiencing opioid-induced respiratory depression.

Correct Answer is ["0.5"]

Explanation

Given:

Dose required = 35 mg

Concentration of medication = 75 mg/mL Formula:

Volume (mL) = Dose required (mg) / Concentration of medication (mg/mL) Calculation:

Volume (mL) = 35 mg / 75 mg/mL Result:

Volume (mL) = 0.4666667 mL Rounded to the nearest tenth:

Volume (mL) ≈ 0.5 mL

A. Constricted pupils B. Increased heart rate C. Bronchial constriction D. Increased GI peristalsis

Correct Answer is B

Explanation

A. Constricted pupils: Adrenergic agonist drugs typically cause pupil dilation (mydriasis), not constriction.
B. Increased heart rate: Adrenergic agonists stimulate the sympathetic nervous system, leading to increased heart rate (positive chronotropic effect) and increased cardiac contractility (positive
inotropic effect).

C. Bronchial constriction: Adrenergic agonists typically cause bronchodilation, not constriction.

D. Increased GI peristalsis: Adrenergic agonists usually inhibit GI motility, leading to decreased GI peristalsis and potentially constipation
