A nurse is transcribing a new prescription in a client's medical record for enoxaparin 30 milligrams, subcutaneously every 12 hours. Which of the following documentation should the nurse use?

Enoxaparin 30 mg SQ q AM and q HS

Enoxaparin 30 mg subcut every 12 hr

Enoxaparin 30 mcg SC q12 hour

Enoxaparin 30 mg sub q every AM and HS

Answer and Explanation

The Correct Answer is B

Choice A reason: "SQ q AM and q HS" is incorrect because it specifies morning and bedtime administration rather than every 12 hours. This could lead to dosing errors.

Choice B reason: "Enoxaparin 30 mg subcut every 12 hr" is the correct documentation. It uses standard terminology, specifies the correct dose, route, and frequency, and avoids abbreviations that could be misinterpreted.

Choice C reason: "30 mcg" is incorrect because it changes the dosage from milligrams to micrograms, which is a thousand-fold difference. This would result in a dangerous underdose.

Choice D reason: "sub q every AM and HS" is incorrect because it specifies administration twice daily at morning and bedtime rather than strictly every 12 hours. This could cause uneven dosing intervals.

Correct Answer is C

Explanation

Choice A reason: Hydrogen peroxide has limited effectiveness against bloodborne pathogens and is not the recommended agent for cleaning blood-contaminated surfaces. It may disinfect minor wounds but is not suitable for environmental cleaning of biohazard spills.

Choice B reason: Isopropyl alcohol is effective against many bacteria and viruses but is not recommended for cleaning large blood spills. Alcohol evaporates quickly and does not reliably inactivate all bloodborne pathogens such as hepatitis B or HIV when used on contaminated surfaces.

Choice C reason: Chlorine bleach is the recommended agent for cleaning surfaces contaminated with blood. A diluted bleach solution (usually 1:10 ratio) effectively kills bloodborne pathogens, including hepatitis B, hepatitis C, and HIV. It is widely used in healthcare settings for environmental decontamination.

Choice D reason: Chlorhexidine is an antiseptic used for skin preparation and wound cleansing. It is not appropriate for cleaning environmental surfaces contaminated with blood. Its use is limited to patient care, not environmental disinfection.

A. Tachycardia B. Urine output of 850 mL per day C. Serum sodium level of 130 mEq/L (136 to 145 mEq/L) D. Distended neck veins while in a sitting position

Correct Answer is A

Explanation

Choice A reason: Tachycardia is a classic sign of dehydration. When fluid volume decreases, cardiac output drops, and the body compensates by increasing heart rate to maintain perfusion. This makes tachycardia a reliable indicator of dehydration in a client with prolonged vomiting.

Choice B reason: A urine output of 850 mL per day is within normal limits (normal adult urine output is 800–2000 mL/day). Dehydration would typically present with oliguria, defined as less than 400 mL/day. Therefore, this finding does not indicate dehydration.

Choice C reason: A serum sodium level of 130 mEq/L indicates hyponatremia, which can occur with excessive vomiting and fluid loss. However, hyponatremia is not a direct indicator of dehydration; it reflects electrolyte imbalance. Dehydration is more directly identified by clinical signs such as tachycardia, hypotension, and dry mucous membranes.

Choice D reason: Distended neck veins suggest fluid overload, not dehydration. In dehydration, neck veins are typically flat or collapsed due to reduced circulating volume. This finding is inconsistent with dehydration.
