A healthcare professional is supervising a newly licensed colleague who is preparing to administer an intramuscular injection. Which of the following actions by the newly licensed colleague requires intervention?

Correct Answer: B

Rationale: The correct answer is B. Administering an intramuscular injection at a 90° angle is essential for proper medication delivery into the muscle tissue. Injecting at a 45° angle is incorrect for intramuscular injections and is typically used for subcutaneous injections where the needle is inserted into the fatty tissue layer beneath the skin. Choice A is correct as selecting a 25-gauge needle is appropriate for an intramuscular injection. Choice C is also correct as the ventrogluteal site is a suitable site for intramuscular injections. Choice D is correct as aspirating for blood return is a necessary step to ensure the needle is not in a blood vessel before injecting the medication.

Correct Answer: D

Rationale: When collecting a stool specimen for ova and parasites, it is essential to place the specimen collection container in a biohazard bag. This practice ensures proper handling of potentially infectious material and prevents contamination with microorganisms. The biohazard bag should be labeled with the client's information for easy identification and proper tracking throughout the testing process. Instructing the client to defecate into a clean container is incorrect as it may introduce contaminants. Transferring the specimen to a sterile container is unnecessary and can increase the risk of contamination. Refrigerating the collected specimen is also not recommended as it may alter the sample and affect the test results.

Correct Answer: D

Rationale: For Mr. Gary's chronic pain at 67, a standardized pain scale (D) best assesses intensity, per pain management standards (e.g., numeric scale). Observation (A) misses subjectivity, description (B) lacks precision, physical assessment (C) is secondary. Scales quantify chronic pain reliably, especially in older adults, making D the optimal choice.

Correct Answer: B

Rationale: For a 6-month-old, an apical pulse of 100 beats per minute falls within the normal range (80-150 bpm), indicating it's safe to administer digoxin, a cardiac glycoside for heart defects, without delay. Recording and calling the physician or holding the dose isn't warranted unless the rate drops below 90-100 bpm (per pediatric guidelines). Rechecking post-administration isn't standard unless symptoms arise. Nurses document and proceed, ensuring timely therapy while monitoring for toxicity signs like bradycardia later.

Correct Answer: C

Rationale: Maslow's hierarchy ranks physiological needs air, water, food, shelter as the most basic, foundational level for survival. Without these, higher needs cannot be pursued; for instance, a patient struggling to breathe (physiological) won't prioritize self-esteem. Physical and psychological isn't a Maslow category; it blends levels imprecisely. Love and belonging (e.g., relationships) is third-tier, reliant on physiological and safety needs being met first. Self-actualization, the top tier, involves personal fulfillment, achievable only after all lower needs are satisfied. In nursing, prioritizing physiological needs like oxygen for a hypoxic patient ensures life-sustaining care precedes emotional or growth-oriented interventions. Maslow's model underscores this hierarchy's logic: physiological stability is the bedrock, making it the most basic need driving human behavior and nursing priorities.

Correct Answer: C

Rationale: Midsagittal plane splits the body into equal left-right halves, unlike horizontal, front-back, or X divisions. Nurses use this in anatomical understanding.

Correct Answer: B

Rationale: When a client is on a soft diet, it is important to offer foods that are easy to chew and swallow. Mashed potatoes are a suitable choice for a soft diet as they are soft in texture and easy to digest. Fresh apples, raw carrots, and nuts are harder and may not be appropriate for a soft diet. Fresh apples and raw carrots require more chewing, and nuts are hard and crunchy, which can be difficult for someone on a soft diet to consume. Therefore, mashed potatoes are the correct option for a client on a soft diet.

Correct Answer: A

Rationale: Oxidative enzyme levels decrease with age, not increase, affecting drug metabolism.

Correct Answer: A

Rationale: Mannitol, an osmotic diuretic, can cause hypotension (A) from fluid shifts and diuresis. Hyperkalemia (B), hyperglycemia (C), or bradycardia (D) are less common. A is correct. Rationale: BP drop risks perfusion; monitoring ensures safety, per pharmacology, critical in brain injury management.
