Petechiae

Answer and Explanation

A: Petechiae are small red or purple spots on the body, caused by minor bleeding from broken capillary blood vessels. This is an objective finding that can be observed and measured by the nurse.

B: Blood pressure is an objective measurement that can be quantified using a sphygmomanometer. It provides numerical data about the patient’s cardiovascular status.

C: Nausea is a subjective symptom reported by the patient. It reflects the patient’s personal experience and cannot be directly observed or measured by the nurse. Subjective data are crucial for understanding the patient’s perspective and symptoms.

Correct Answer is C

Explanation

A: Hypertension is not typically a late sign of hypoxemia. It can occur in various conditions but is not specific to hypoxemia.

B: Tachycardia is an early sign of hypoxemia as the body attempts to compensate for low oxygen levels by increasing the heart rate.

C: Pallor is a late sign of hypoxemia. It indicates poor oxygenation and perfusion, often seen when the body can no longer compensate for the lack of oxygen.

D: Bradypnea, or slow breathing, is not a typical sign of hypoxemia. Hypoxemia usually causes an increase in respiratory rate (tachypnea) as the body tries to take in more oxygen.

A. 20 mg B. 0.20 mg C. 0.2 mg D. 2.0 mg

Correct Answer is C

Explanation

A: 20 mg is incorrect and represents a significant overdose. It is not an appropriate transcription for two tenths of a milligram.

B: 0.20 mg is not the best practice because it can be misread as 20 mg if the decimal point is missed. Leading zeros should be used without trailing zeros to prevent errors.

C: 0.2 mg is the correct transcription. It clearly represents two tenths of a milligram and minimizes the risk of misinterpretation.

D: 2.0 mg is incorrect and represents a tenfold overdose. It is not an appropriate transcription for two tenths of a milligram.
