A nurse is preparing to administer an IM injection for an infant. Which of the following actions should the nurse take?

Administer the medication into the vastus lateralis muscle.

Administer the medication with a 20-gauge needle.

Administer the medication into the deltoid muscle.

Administer the medication over 2 min.

Answer and Explanation

The Correct Answer is A

Rationale:

A. Administer the medication into the vastus lateralis muscle: The vastus lateralis is the preferred site for intramuscular injections in infants because it is well-developed and free of major nerves and blood vessels. This site allows for safe and effective absorption of the medication.

B. Administer the medication with a 20-gauge needle: A 20-gauge needle is too large for infants and can cause unnecessary tissue trauma. A smaller gauge, typically 22–25, is appropriate for IM injections in infants to minimize pain and tissue damage.

C. Administer the medication into the deltoid muscle: The deltoid muscle is underdeveloped in infants, making it unsuitable for IM injections due to limited muscle mass and risk of injury to underlying structures. It is generally used only in older children or adults.

D. Administer the medication over 2 min: IM injections are typically administered at a moderate pace, but a 2-minute administration is unnecessarily slow for infants. Proper technique involves steady, controlled injection without causing excessive discomfort.

Correct Answer is A

Explanation

Rationale:

A. Tachycardia: Tachycardia is common in diabetic ketoacidosis (DKA) due to dehydration, electrolyte imbalances, and compensatory mechanisms for hypotension. The heart rate increases to maintain adequate perfusion in response to fluid loss and acidosis.

B. HCO3 in expected range: In DKA, bicarbonate (HCO3) levels are decreased due to metabolic acidosis. The body uses bicarbonate to buffer excess ketone acids, so HCO3 is typically below the normal range, not within expected limits.

C. Increased PaCO2: In DKA, PaCO2 is usually decreased due to Kussmaul respirations (deep, rapid breathing) as the body attempts to compensate for metabolic acidosis by blowing off CO2. Elevated PaCO2 would indicate hypoventilation, which is not characteristic of DKA.

D. Hyperreflexia: DKA does not typically cause hyperreflexia. Neurological changes, if present, are more likely to involve lethargy, confusion, or coma due to severe acidosis, dehydration, and electrolyte imbalances, rather than exaggerated reflexes.

A. Maintain sensory stimulation for the client. B. Identify stressors that caused the client's aggression. C. Observe the client's range of movement. D. Hold a critical incident debriefing about the client.

Correct Answer is C

Explanation

Rationale:

A. Maintain sensory stimulation for the client: While in restraints, minimizing overstimulation is important to reduce agitation and prevent further aggressive behavior. Excessive sensory input can increase stress and escalate the situation rather than support safety.

B. Identify stressors that caused the client's aggression: Understanding triggers is important for long-term behavior management, but it is not the priority while the client is physically restrained. Immediate safety and monitoring take precedence over retrospective analysis.

C. Observe the client's range of movement: Continuous monitoring of the client’s range of motion is essential while restraints are in place to prevent injury, nerve damage, or impaired circulation. Regular checks ensure the restraints are applied safely and that the client maintains mobility as much as possible within safety limits.

D. Hold a critical incident debriefing about the client: Debriefing is important for staff learning and emotional processing after the event, but it occurs after the client is safe and restraints are removed. It is not an action to be performed while the client is restrained.
