A client reports feeling numbness and tingling in the extremities. Which of the client's serum laboratory values should the practical nurse (PN) review before reporting the finding?
White blood cell count (WBC).
Hematocrit
Albumin and protein.
Electrolytes
None
None
The Correct Answer is D
The correct answer is D. Electrolytes.
Choice A rationale: The white blood cell count (WBC) is typically reviewed for signs of infection or inflammation, but it is not directly related to numbness and tingling.
Choice B rationale: Hematocrit levels assess the proportion of red blood cells in the blood, which are not commonly associated with numbness and tingling.
Choice C rationale: Albumin and protein levels are important for nutritional status and overall health but are not directly associated with numbness and tingling.
Choice D rationale: Electrolytes are crucial for nerve function and muscle contractions. Abnormal levels of electrolytes (such as calcium, potassium, or sodium) can lead to symptoms like numbness and tingling in the extremities.

Correct Answer is A
Explanation
The correct answer is choice A: Never scratch under the cast.
Choice A rationale:
It is important not to scratch under the cast because inserting objects can lead to skin injury and infection. If itching occurs, blowing cool air from a hair dryer into the cast is recommended.
Choice B rationale:
While mild swelling and some discomfort are common after a cast is applied, patients should not expect an increase in pain. Persistent or severe pain could indicate complications such as increased swelling, decreased blood flow, or pressure on nerves and should be evaluated by a healthcare provider.
Choice C rationale:
Applying a cold pack to “hot spots” on the cast is not recommended as it can lead to moisture accumulation and skin problems. Instead, to manage swelling and discomfort, ice can be applied over the cast, covered with a thin towel, for 20 minutes every two hours while awake during the first 48 hours.
Choice D rationale:
Keeping the injured leg in a dependent position is not advised because it can increase swelling and pain. The affected limb should be elevated above the level of the heart to reduce swelling and promote healing.
Correct Answer is C
Explanation
Croup is a respiratory infection that causes inflammation and narrowing of the airway, resulting in a barking cough, hoarseness, and stridor. The PN should monitor the child's oxygen saturation level via pulse oximetry, as it can indicate the severity of the airway obstruction and the need for supplemental oxygen or other interventions.
The other options are not correct because:
A. Instructing the mother to play with the child for stimulation and distraction may worsen the child's condition, as it can increase his respiratory demand and anxiety.
B. Administering a dose of acetaminophen as needed may help reduce fever or pain, but it does not address the underlying cause of croup or improve airway patency.
D. Encouraging the child to drink adequate amounts of fluids may help prevent dehydration and thin the secretions, but it does not relieve the inflammation or narrowing of the airway.
