A nurse is discussing immunity with a client who has received an immunization. The nurse should identify that an immunization functions as part of which type of immunity?

Correct Answer: C

Rationale: The correct answer is C: Acquired immunity. Acquired immunity occurs when an individual is given a vaccine or immunization to develop antibodies. This type of immunity is specific and develops after exposure to an antigen. Innate immunity (choice A) is the body's natural defense system present at birth. Passive immunity (choice B) is temporary immunity passed from one individual to another. Natural immunity (choice D) refers to immunity that is not gained through medical intervention or deliberate exposure.

Correct Answer: C

Rationale: The correct answer is to discard the medication with another nurse as a witness. Controlled substances, such as narcotic medications, must be properly disposed of to prevent misuse or diversion. Having another nurse witness the disposal ensures accountability and follows proper protocols. Storing the unused medication for later use (Choice A) is unsafe and could lead to misuse. Discarding the medication in a regular trash bin (Choice B) is inappropriate as it does not ensure proper disposal of a controlled substance. Reporting the unused portion to the provider (Choice D) is not the immediate action needed for proper medication disposal.

Correct Answer: B

Rationale: The correct answer is B. Reducing fluid intake before bedtime helps prevent interruptions in sleep due to bathroom visits, which is crucial for individuals with insomnia. Taking naps throughout the day (choice A) may disrupt nighttime sleep. Drinking coffee (choice C) is counterproductive as it contains caffeine, which can interfere with falling asleep. Increasing screen time before bed (choice D) can negatively impact sleep quality due to the stimulating effects of screens.

Correct Answer: A

Rationale: The correct answer is A: 90-degree angle. The ventrogluteal site is preferred for intramuscular injections because it is away from major nerves and blood vessels. Administering the injection at a 90-degree angle ensures that the medication reaches deep into the muscle tissue, allowing for proper absorption of the drug. Choice B, 60-degree angle, is incorrect as it is not the recommended angle for the ventrogluteal site. Choice C, 75-degree angle, and Choice D, 45-degree angle, are also incorrect as they are not the appropriate angles for administering an intramuscular injection using the ventrogluteal site.

Correct Answer: A

Rationale: Before administering blood products, assessing the patient's temperature is crucial. This action provides baseline data to detect any febrile reactions during or after the transfusion. Fever may indicate a transfusion reaction, so continuous monitoring of vital signs is essential throughout the procedure. Documenting the patient's response (choice B) is important but comes after assessing the temperature. Priming IV tubing with 0.45% sodium chloride (choice C) is not directly related to the initial action required before administering blood products. Administering epinephrine (choice D) is not indicated unless there is a severe allergic reaction, which is not the standard initial step before blood product administration.
