Nursing Elites

1. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?

• A. Decreased calcium
• B. Elevated potassium
• C. Increased sodium
• D. Low hemoglobin

Correct answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.

2. When changing the client's dressing, which observation should the nurse report to the client's surgeon for a client recovering from an appendectomy for a ruptured appendix with a surgical wound healing by secondary intention?

• A. A halo of erythema on the surrounding skin
• B. Presence of serous drainage
• C. Edema around the wound
• D. Absence of granulation tissue

Correct answer: A

Rationale: A halo of erythema on the surrounding skin may indicate an infection or inflammation of the wound site, which is critical to report to the surgeon. Erythema, redness, and warmth are signs of inflammation that could potentially be a sign of an infected wound. Serous drainage is a common and expected finding in healing wounds, indicating a normal healing process. Edema around the wound might be expected due to the body's response to tissue injury. The absence of granulation tissue in a wound healing by secondary intention may not be an immediate concern as it forms during the later stages of wound healing.

3. While caring for a client receiving parenteral fluid therapy via a peripheral IV catheter, after which of the following observations should the nurse remove the IV catheter?

• A. Swelling and coolness are observed at the IV site.
• B. The client reports mild discomfort at the insertion site.
• C. The infusion rate is slower than expected.
• D. The IV catheter is no longer needed for treatment.

Correct answer: A

Rationale: Swelling and coolness at the IV site can indicate complications such as infiltration, which can lead to tissue damage or fluid leakage into the surrounding tissues. Prompt removal of the IV catheter is essential to prevent further complications. The client reporting mild discomfort at the insertion site is common during IV therapy and does not necessarily warrant catheter removal unless there are signs of infiltration. A slower than expected infusion rate may not always necessitate IV catheter removal; the nurse should troubleshoot potential causes such as kinks in the tubing or pump malfunctions first. Just because the IV catheter is no longer needed for treatment does not automatically mean it should be removed; proper assessment and monitoring for complications are still essential.

4. 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.

5. A client needs to maintain a positive nitrogen balance for wound healing. Which of the following food items should the nurse recommend as a good source of complete protein?

• A. Cheddar cheese
• B. White rice
• C. Apples
• D. Green beans

Correct answer: A

Rationale: Cheddar cheese is the correct answer as it is a good source of complete protein that contains all essential amino acids required for maintaining a positive nitrogen balance for wound healing. Complete proteins provide all essential amino acids needed by the body. White rice, apples, and green beans do not offer complete proteins like cheddar cheese, making them inadequate choices for this purpose.
