A nurse is preparing to administer ondansetron 0.15 mg/kg IV to a child who is receiving chemotherapy and weighs 29.4 kg. Available is ondansetron 4 mg/2 mL solution. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.2"]
To calculate the dose of ondansetron for a child who is receiving chemotherapy, the nurse needs to use the following formula:
Dose (mL) = (Dose ordered in mg / Dose available in mg) x Volume available in mL
In this case, the dose ordered in mg is 0.15 mg/kg x 29.4 kg, which equals 4.41 mg. The dose available in mg is 4 mg, and the volume available in mL is 2 mL. Therefore, the dose in mL is:
Dose (mL) = (4.41 mg / 4 mg) x 2 mL Dose (mL) = 2.205 mL
The nurse should round the answer to the nearest tenth, so the final answer is 2.2 mL. The nurse should administer 2.2 mL of ondansetron IV to the child who is receiving chemotherapy.

Correct Answer is B

B. Correct. It is common for preschool-age children to be curious about what happens to the body after death. This curiosity is an age-appropriate response to death.
C. A preschool-age child may not fully grasp the concept of death as permanent. They may have limited understanding of the irreversibility of death.

Correct Answer is B
Explanation
A. "You should notify your provider if your testes are firm and egg shaped." This statement does not provide specific guidance on when or how to perform the examination. It also describes a normal shape of the testes.
B. This is the correct statement. Performing the testicular self-examination following a warm shower helps relax the scrotal tissue, making it easier to detect any abnormalities or changes.
C. "If you feel a hard lump, wait 1 month and retest yourself." This is not advisable. If a hard lump is detected during a testicular self-examination, the individual should promptly notify their healthcare provider for further evaluation.
D. "You should perform the examination once every other month." While regular
testicular self-examinations are important, it is generally recommended to perform them monthly, not once every other month.
