A nurse is caring for a client who is confused and has been placed in wrist restraints.
Which of the following actions should the nurse take while caring for this client? (Select all that apply.)

The correct answer is Choice D

Choice A rationale: A 1-inch needle is typically used for intramuscular injections, not intradermal administration. Intradermal injections require a short, fine-gauge needle—usually ¼ to ⅝ inch in length and 25 to 27 gauge—to ensure accurate placement within the dermis. Using a longer needle increases the risk of injecting into subcutaneous tissue, which alters absorption and invalidates the test. Scientific technique demands precise needle selection based on anatomical depth and pharmacokinetics of the test substance.

Choice B rationale: A 20° angle is inappropriate for intradermal injections, which require a shallow angle of 5° to 15° to ensure deposition within the dermal layer. Angles greater than 15° risk penetrating into subcutaneous tissue, compromising test accuracy and absorption kinetics. The dermis is a narrow layer between the epidermis and subcutaneous fat, and precise angulation is critical for forming the characteristic wheal and ensuring localized immune response. Scientific technique mandates strict adherence to angle parameters.

Choice C rationale: The standard volume for a tuberculin skin test using purified protein derivative (PPD) is 0.1 mL, not 0.5 mL. Administering 0.5 mL would exceed the recommended dose, potentially causing excessive local reaction, invalid test results, and patient discomfort. The Mantoux method requires exact dosing to elicit a controlled immune response for accurate interpretation. Scientific protocol emphasizes precision in volume to maintain test validity and minimize adverse effects. Overdosing violates established guidelines.

Choice D rationale: Pinching or gently pulling the skin taut at the injection site stabilizes the dermal layer and facilitates correct needle placement. This technique ensures the needle enters at the proper angle and depth, allowing formation of a visible wheal, which confirms intradermal delivery. It also minimizes patient discomfort and prevents misplacement into deeper tissues. Scientific technique for intradermal injections prioritizes anatomical control and tactile feedback to optimize accuracy and diagnostic reliability.

Choice A rationale

While involving the family in the care of an older adult client is important, calling the family to make arrangements for someone to sit with the client is not the immediate action the nurse should take. The nurse’s first responsibility is to ensure the client’s safety and well-being.
Choice B rationale
Obtaining a prescription for medication to sedate the client is not the immediate action the nurse should take. Sedating the client does not address the immediate concern of potential injury.
Choice C rationale
The nurse should first check the client for injuries. This is the immediate action because the client may have sustained injuries from the fall. The nurse should perform a thorough assessment to determine the extent of any injuries and provide appropriate care.
Choice D rationale
Assisting the client back into bed and applying restraints is not the immediate action the nurse should take. Restraints should be used as a last resort and only if less restrictive measures have been ineffective. Furthermore, restraints require a physician’s order.
