How should a healthcare professional administer a subcutaneous injection?

Correct Answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.

Correct Answer: A

Rationale: The correct answer is to apply a hydrocolloid dressing. This type of dressing helps maintain a moist environment that is conducive to healing in stage 3 pressure ulcers. Providing wound debridement (choice B) is more suitable for higher stages of pressure ulcers where there is necrotic tissue. Changing the dressing daily (choice C) may be necessary but is not the primary action for a stage 3 pressure ulcer. Applying moist gauze (choice D) is not the recommended approach as it does not provide the same benefits as a hydrocolloid dressing.

Correct Answer: C

Rationale: Administering fluids is the appropriate action for a healthcare provider to take when a patient has a high fever and is disoriented. Dehydration can worsen confusion and other symptoms in such a situation. Administering acetaminophen or cooling the patient with cold compresses may help reduce the fever but does not address the underlying issue. Administering antibiotics is not indicated for a high fever and disorientation without knowing the cause.

Correct Answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for anaphylactic shock as it helps reverse the severe allergic reaction by constricting blood vessels, increasing heart rate, and opening airways for improved breathing. Oxygen (Choice B) can be administered after epinephrine to support oxygenation. Corticosteroids (Choice C) may be used to prevent a biphasic reaction but are not the initial intervention. Antihistamines (Choice D) can help with itching and hives but do not address the life-threatening symptoms of anaphylaxis.

Correct Answer: A

Rationale: Administering oxygen is the most appropriate action when a patient is experiencing confusion after surgery because it helps alleviate hypoxia, which may be causing the patient's confusion. Repositioning the patient would not directly address the potential hypoxia issue. Administering IV fluids may be necessary for hydration or other reasons but is not the initial priority in addressing confusion post-surgery. Performing a neurological exam may be important later on to assess the patient's neurological status but should not be the first action taken when confusion is present.
