Nursing Elites

1. A client has a new prescription for parenteral nutrition (PN) in 20% dextrose and fat emulsions. Which of the following is an appropriate action to include in the plan of care?

• A. Monitor blood glucose levels daily.
• B. Change the PN infusion bag every 24 hours.
• C. Prepare the client for a central venous line.
• D. Administer the PN and fat emulsion together.

Correct answer: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.

2. The healthcare provider is preparing to administer a subcutaneous injection of heparin. Which site is most appropriate for the healthcare provider to use?

• A. Deltoid muscle
• B. Ventrogluteal site
• C. Abdomen
• D. Dorsogluteal site

Correct answer: C

Rationale: The abdomen is the most appropriate site for administering subcutaneous heparin injections. The abdomen has a layer of subcutaneous fat and a good blood supply, making it an ideal site for subcutaneous injections. Using the deltoid muscle for heparin injections is not appropriate as it is typically used for intramuscular injections. The ventrogluteal site is more suitable for intramuscular injections rather than subcutaneous injections. The dorsogluteal site is no longer recommended for injections due to the risk of injury to the sciatic nerve.

3. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

4. A client is receiving discharge instructions for using a walker. Which statement indicates an understanding of the teaching?

• A. I will hire someone to trim the tree that hangs low over the stairs of my front porch.
• B. I will avoid using the walker on uneven surfaces.
• C. I will use the walker on stairs for added support.
• D. I will not need to make any changes to my home environment.

Correct answer: A

Rationale: The correct answer is A because hiring someone to trim low-hanging branches over stairs ensures home safety and reflects an understanding of walker use. This action indicates the client's awareness of potential hazards and the importance of a safe environment for walker use. Choice B is incorrect as avoiding uneven surfaces is a general safety precaution but does not directly relate to walker use and does not demonstrate an understanding of the teaching. Choice C is incorrect because using a walker on stairs is not recommended due to safety concerns such as balance and fall risks. Choice D is incorrect as making no changes to the home environment may pose safety risks when using a walker, showing a lack of understanding regarding safety precautions needed for walker use.

5. The healthcare professional is preparing to administer a tuberculin skin test. Which site is most appropriate for this injection?

• A. Deltoid muscle
• B. Vastus lateralis muscle
• C. Abdomen
• D. Inner forearm

Correct answer: D

Rationale: The inner forearm is the most appropriate site for administering a tuberculin skin test. This test requires an intradermal injection, which is administered just below the surface of the skin. The inner forearm provides a flat, easily accessible surface for this type of injection. Choices A, B, and C are incorrect because the tuberculin skin test should not be administered into a muscle (deltoid muscle or vastus lateralis muscle) or into the abdomen. The test requires precise placement within the dermal layer of the skin on the inner forearm to accurately assess for a reaction.
