Question 1 of 5
Often children are monitored with pulse oximeter. The pulse oximeter measures the:
Correct Answer: B
Rationale: The O2 content of whole blood is determined by the partial pressure of oxygen (PO2) and the oxygen saturation. The pulse oximeter does not measure the PO2. The pulse oximeter is a noninvasive method of measuring the arterial oxygen saturation. The PO2 is the amount of O2 dissolved in plasma, which the pulse oximeter does not measure. The affinity of hemoglobin for O2 is the relationship between oxygen saturation and PO2 and is not measured by the pulse oximeter.

A client with a history of chronic venous insufficiency is admitted with complaints of leg ulcers. The nurse should give priority to:
Correct Answer: A

Correct Answer: C
Rationale: Morphine sulfate, a narcotic analgesic, causes sedation and a decrease in level of consciousness. The side effects of morphine sulfate include respiratory depression. Morphine sulfate causes peripheral vasodilation, which decreases afterload, producing a decrease in the myocardial workload. Morphine sulfate alters the perception of pain through an unclear mechanism. This alteration promotes pain relief.

A child is admitted with severe headache, fever, vomiting, photophobia, drowsiness, and stiff neck associated with viral meningitis. She will be more comfortable if the nurse:
Correct Answer: A
Rationale: The discomfort of photophobia is alleviated by dimming the lights. Helping the child to breathe slowly and deeply may help to reduce anxiety, but it will not alleviate other discomforts of viral meningitis. It is important to maintain fluid balance, but sips of warm liquids do not alleviate the discomforts of meningitis. A large, soft pillow under her head causing neck flexion is likely to increase her discomfort owing to stretching of the meninges.
