Naloxone is effective because of which action?

Increasing the excretion of morphine sulfate by altering serum pH.

Preventing activation of opioid receptors through antagonist actions.

Regulating the sensitivity of opioid receptors by neurochemical alterations.

Countering the effects of morphine sulfate by agonist actions.

Answer and Explanation

The Correct Answer is B

a) Naloxone does not increase the excretion of opioids by altering serum pH; its primary action is at the receptor level.

b) Naloxone is an opioid receptor antagonist, meaning it blocks or prevents the activation of opioid receptors. This is how it counteracts the effects of opioids like morphine.

c) Naloxone does not regulate the sensitivity of opioid receptors by neurochemical alterations. Its action is more direct as an antagonist.

d) Naloxone is not an agonist; it does not produce opioid-like effects. Instead, it competes with opioids for receptor binding and blocks their effects.

Correct Answer is ["A","C","D"]

Explanation

a. This statement warrants further education because enteric-coated aspirin is specifically designed to be absorbed in the small intestine and should not be chewed. Chewing the enteric coated aspirin can interfere with its protective coating and may lead to stomach irritation.

b. This statement is correct. Taking the aspirin with food can help minimize stomach irritation.

c. This statement warrants further education. Aspirin, even in low doses, should not be given to young children without consulting a healthcare provider due to the risk of Reye's syndrome.

d. This statement warrants further education. Ringing in the ears (tinnitus) is not a normal side effect of aspirin, and persistent symptoms should be reported to the healthcare provider.

e. This statement is correct. Black, tarry stools can indicate gastrointestinal bleeding, and the healthcare provider should be notified promptly.

A. Blood pressure of 92/44 mmHg B. Respiratory rate of 26 breaths per minute C. Heart rate of 92 beats per minute D. Oxygen saturation level of 95% on room air

Correct Answer is A

Explanation

A) The nurse should hold the administration of oral metoprolol 25 mg if the blood pressure of the patient is 92/44 mmHg, as this indicates hypotension, which can be worsened by the beta blocker effect of metoprolol.

B) A respiratory rate of 26 breaths per minute is within the acceptable range for administering metoprolol.

C) A heart rate of 92 beats per minute is within the acceptable range for administering metoprolol.

D) Holding the administration of metoprolol may be appropriate if the oxygen saturation level is low. Metoprolol is primarily used for heart rate and blood pressure control and may not be the immediate concern in a client with low oxygen saturation. The healthcare provider should be consulted for further guidance.
