When teaching a client about insulin therapy, the nurse should instruct the client to avoid which over-the- counter preparation that can interact with insulin?

Correct Answer: D

Rationale: Salicylates, such as aspirin, can potentiate the hypoglycemic effects of insulin. They can increase insulin sensitivity and potentially lead to low blood sugar levels (hypoglycemia). Therefore, clients using insulin should avoid over-the-counter salicylate preparations to prevent this interaction and the risk of hypoglycemia. It is important for clients to always consult healthcare professionals before taking any new medications or over-the-counter preparations when using insulin therapy.

Correct Answer: C

Rationale: The Glasgow Coma Scale (GCS) is a neurological scale that is used to assess the level of consciousness in patients. It is based on three factors: eye opening, verbal response, and motor response. Each factor is scored on a scale of 1 to 4 or 6, with a lower total score indicating a lower level of consciousness.

Correct Answer: A

Rationale: The nurse will assess a loss of ability in the area of balance. Balance is an essential component of the physical function that allows individuals to maintain an upright posture and stability during movement. A loss of balance can significantly impact a person's mobility, coordination, and safety. Nurses often assess balance as part of their evaluations to identify any impairments that may affect a patient's independence and daily activities.

Correct Answer: D

Rationale: For an adult receiving total parenteral nutrition (TPN), it is essential for the nurse to monitor fluid and electrolyte levels closely. TPN provides all essential nutrients, including fluids and electrolytes, directly into the bloodstream. Monitoring these levels is crucial to prevent potential complications such as fluid overload, electrolyte imbalances, and hyperglycemia. Assessing and maintaining appropriate fluid and electrolyte balance are essential components of managing a patient receiving TPN to ensure optimal patient outcomes.

Correct Answer: C

Rationale: Before drawing blood from a central venous catheter like a Hickman type, it is essential to ensure that the catheter is patent and free of any clots. Flushing the catheter with a heparinized solution (to prevent clot formation) before withdrawing blood helps clear the catheter and ensures accurate blood sample collection. Removing clots or obstructions from the catheter is crucial to prevent complications and maintain the catheter's function. Therefore, it is important to first flush the catheter with a heparinized solution before drawing blood from it.
