After administering an intradermal (ID) injection for a skin test, the nurse notices a small bleb at the injection site. The best action for the nurse to take at this time is to:

Correct Answer: C

Rationale: The formation of a small bleb is expected after an ID injection for skin testing. The other actions are not appropriate.

Correct Answer: B

Rationale: Position the inhaler to an open mouth, with the inhaler 1 to 2 inches away from the mouth, or attach a spacer to the mouthpiece of the inhaler, or place the mouthpiece in the mouth. To administer, press down on the inhaler to release the medication while inhaling slowly. Wait 1 to 2 minutes between puffs if a second puff of the same medication has been ordered.

Correct Answer: B

Rationale: The calculation is as follows: 2 mg : 1 mL = 1.5 mg : x mL. Solving for x: (2 × x) = (1 × 1.5); 2x = 1.5; x = 0.75. Therefore, the nurse will administer 0.75 mL.

Correct Answer: B

Rationale: The standard initial dose of dantrolene for malignant hyperthermia is 2.5 mg/kg IV, repeated as needed up to a maximum of 10 mg/kg. For a 70 kg patient, 2.5 mg/kg × 70 kg = 175 mg initially. However, the total dose may reach 10 mg/kg × 70 kg = 700 mg. Given the options, 600 mg is closest to a practical total dose in a crisis, though typically it’s administered in increments. (Note: Multiple '600 mg' listings appear to be an OCR error; only one is valid.)

Correct Answer: A

Rationale: Slough is dead tissue that is shed from the surface of the wound. It may be white, yellow, green, or brown in color and may have a soft, moist, or dry texture. It should be removed to promote wound healing.
