Correct Answer: C

Rationale: The correct answer is to insert the catheter at a 15-degree angle. This angle allows for easier venous access by ensuring proper catheter placement into the vein. Applying a tourniquet above the insertion site can help distend the vein for better visualization but is not the immediate action required for the insertion process. Shaving the area around the insertion site is not necessary unless there is excessive hair that may interfere with the insertion. Using an 18-gauge needle for insertion is a specific detail related to the equipment rather than the technique of insertion.

Correct Answer: C

Rationale: The correct answer is C: Sodium 140 mEq/L. An elevated sodium level can affect the effectiveness of digoxin therapy and may lead to toxicity. Therefore, it is crucial to report this value to the provider. Potassium, calcium, and magnesium levels are important as well, but elevated sodium can have a more direct impact on digoxin therapy in this scenario.

Correct Answer: C

Rationale: In a client with thrombocytopenia, the platelet count is low, leading to a risk of bleeding. Providing a stool softener is essential to prevent constipation and straining during bowel movements, which can reduce the risk of bleeding episodes. Encouraging the client to floss daily (Choice A) is a good oral hygiene practice but is not directly related to thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is related to infection control but does not address the specific risk of bleeding in thrombocytopenia. Avoiding serving the client raw vegetables (Choice D) is important in clients with neutropenia to prevent infections, not in thrombocytopenia.

Correct Answer: A

Rationale: The correct answer is A: "Glucose 180 mg/dL." Elevated glucose levels in a client receiving TPN may indicate hyperglycemia, which can lead to complications such as osmotic diuresis, dehydration, and electrolyte imbalances. It is essential to report this finding to the provider for further evaluation and management. Choices B, C, and D are within normal ranges and do not indicate immediate concerns related to TPN administration.

Correct Answer: A

Rationale: Corrected Rationale: Providing information about stress management is essential when caring for a client with Raynaud's disease because stress can trigger episodes. Stress management techniques can help the client avoid triggers and reduce the frequency of episodes. Choice B is incorrect because maintaining a warm temperature, rather than a cool one, helps prevent vasoconstriction and can be beneficial for clients with Raynaud's disease. Choice C is incorrect because epinephrine is not a standard treatment for Raynaud's disease; it is more commonly used for severe allergic reactions. Choice D is incorrect because glucocorticoid steroids are not typically used in the management of Raynaud's disease.
