Correct Answer: A

Rationale: The correct answer is A: Deltoid and vastus lateralis. These sites are safe for intramuscular injections due to their large muscle mass and fewer major blood vessels and nerves. The deltoid muscle is located on the upper arm, while the vastus lateralis is on the thigh, making them easily accessible and suitable for injections. The dorsogluteal and ventrogluteal sites may have risks of hitting major blood vessels and nerves, leading to complications. Upper chest and abdomen (choice
B) are not recommended for intramuscular injections due to the proximity of vital organs. Inner forearm and scapular area of the back (choice
C) have fewer muscle mass and more nerves and blood vessels. Lower leg (choice
D) is not ideal for intramuscular injections due to the risk of hitting major blood vessels and nerves.

Correct Answer: A

Rationale: The correct answer is A. Acetaminophen is primarily metabolized by the liver. Patients with a history of alcohol abuse have impaired liver function, making them more susceptible to acetaminophen-induced liver damage. Additionally, hepatitis C can further compromise liver function, increasing the risk.
Choice B is incorrect as COPD and smoking history do not directly impact liver metabolism of acetaminophen.
Choice C is incorrect as type 2 diabetes and end-stage renal disease do not significantly affect liver metabolism of acetaminophen.
Choice D is unrelated to liver function and acetaminophen metabolism.

Correct Answer: D

Rationale: The correct answer is D: Call the pharmacy for a new bottle of the medication. The rationale is as follows: The expiration date on the bottle has passed, indicating that the medication may have degraded and may not be effective. It is crucial to ensure that the medication is potent and safe for the patient's use.
Therefore, the best course of action is to obtain a new bottle of medication from the pharmacy to ensure the patient's safety and the effectiveness of the treatment. Administering expired medication can be harmful and ineffective.

Summary of other choices:
A: Administering one-half tablet does not guarantee the full 40-mg dose required.
B: Administering two tablets would result in a 40-mg dose, but the expired medication may not be effective.
C: Calling the pharmacy to see if 40-mg tablets are available does not address the issue of the expired medication.
E, F, G: Not relevant to the situation.

Correct Answer: D

Rationale: The correct answer is D (8:45 and 9:15 A.M.). Administering the medication within this time frame ensures that it is given neither too early nor too late. By choosing a narrower window like option D, the nurse minimizes the risk of error and ensures the medication's effectiveness. Options A (8:00 and 10:00 A.M.), B (8:30 and 9:30 A.M.), and C (8:30 and 9:00 A.M.) provide wider time frames, increasing the chances of administering the medication outside the ideal window. This could potentially lead to suboptimal therapeutic effects or adverse reactions.
Therefore, option D is the most precise and safe choice for medication administration.

Correct Answer: D

Rationale: The correct answer is D: Standing. A standing order is a pre-established protocol for a specific situation or condition, such as all patients admitted to the cardiac unit getting an EKG unless otherwise ordered. This type of order is routine and does not require specific authorization each time.

A: PRN orders are given as needed, not pre-established like in this case.
B: One-time orders are for a single occurrence, not a routine protocol like in the scenario.
C: STAT orders are for immediate attention, not a routine protocol like in this scenario.
