A nurse is reviewing the laboratory values for an adolescent who is scheduled for a surgical procedure.
For which of the following laboratory values should the nurse notify the provider?
Platelet count 120,000/mm².
WBC count 9,800/mm³.
Hgb 13 mg/dL.
Hct 42%.
The Correct Answer is A
The nurse should notify the provider because this value is lower than the normal range of 150,000 to 450,000 platelets per microliter of blood. A low platelet count can indicate a risk of bleeding or a condition such as thrombocytopenia or disseminated intravascular coagulation (DIC).
Choice B is wrong because WBC count 9,800/mm³ is within the normal range of 4,500 to 11,000 cells per microliter of blood.
Choice C is wrong because Hgb 13 mg/dL is within the normal range of 12 to 16 mg/dL for females and 14 to 18 mg/dL for males.
Choice D is wrong because Hct 42% is within the normal range of 37% to 47% for females and 42% to 52% for males.

Correct Answer is D
Explanation
Dysrhythmia is an abnormal heart rhythm that can be a sign of severe lithium toxicity.
Lithium toxicity can occur when a person takes too much lithium, a mood- stabilizing medication used to treat bipolar disorder and major depressive disorder.
Choice A is wrong because hypoglycemia is not a symptom of lithium toxicity. Hypoglycemia is low blood sugar that can cause symptoms such as shakiness, sweating, hunger, and confusion.
Choice B is wrong because excess salivation is not a symptom of lithium toxicity. Excess salivation can be caused by various factors, such as infections, medications, or nerve damage.
Choice C is wrong because urinary retention is not a symptom of lithium toxicity. Urinary retention is the inability to empty the bladder completely, which can cause pain, discomfort, and infection. Lithium toxicity can actually cause increased urine output, not decreased.
Normal ranges for blood lithium levels are 0.6 to 1.2 mEq/L for maintenance therapy and 0.8 to 1.5 mEq/L for acute therapy. Levels above 1.5 mEq/L can cause mild to moderate toxicity, and levels above 2.0 mEq/L can cause severe toxicity. Levels above 3.0 mEq/L are considered a medical emergency.
Correct Answer is B
Explanation
Ask the client to empty their bladder.
This is because a full bladder can interfere with the pelvic examination and cause discomfort to the client. The nurse should also instruct the client to avoid douching, using tampons, vaginal medications, sprays, powders, birth control foam, cream, or jelly for at least 24 hours before the exam.
Choice A is wrong because the client should be placed in a lithotomy position, not a prone position, for a pelvic examination.
Choice C is wrong because douching can alter the normal vaginal flora and pH, and increase the risk of infection.
Choice D is wrong because placing the client’s arms over their head can tighten the abdominal muscles and make the examination more difficult. The nurse should ask the client to place their arms at their sides or across their chest.
