A nurse is preparing to measure a client’s level of oxygen saturation on a patient who has had a bilateral lower leg amputation. He noticed the patient’s hands are very edematous.
The nurse should apply the pulse oximeter probe to which of the following locations?
Skin fold
Toe
Earlobe
Finger
The Correct Answer is C
A. Skin fold:
This may not be the best choice in this situation because the skin fold might not provide an accurate reading, especially if the hands are edematous.
B. Toe:
While the toe is a common site for pulse oximetry, in a patient with bilateral lower leg amputations, it might not be the most practical option. The nurse might face challenges in securing the pulse oximeter probe on the toe, and the accuracy of the reading could be affected.
C. Earlobe:
This is often a suitable alternative site for pulse oximetry when peripheral perfusion is compromised in the extremities. In this case, with bilateral lower leg amputations and edematous hands, applying the pulse oximeter probe to the earlobe is a good choice.
D. Finger:
In a patient with edematous hands, the finger might not be the best choice as the edema could affect the accuracy of the measurement. Additionally, if the patient has lower leg amputations, using the earlobe or another alternative site may be more appropriate.

Correct Answer is ["6"]
Explanation
To calculate the amount of ampicillin needed for one dose, we need to use a proportion. We can set up the proportion as follows:
150 mg / x mL = 125 mg / 5 mL
We can cross-multiply and solve for x:
150 * 5 = 125 * x
750 = 125 * x
x = 750 / 125
x = 6
Therefore, we need 6 mL of ampicillin for one dose
Correct Answer is A
Explanation
A. Take the blood pressure:
Assessing blood pressure is a critical initial step when a patient is experiencing dyspnea. It helps provide information about the patient's overall cardiovascular status, which is essential in determining the severity of the dyspnea and guiding subsequent interventions.
B. Remove the pillow from under the patient’s head:
Removing the pillow may be a relevant intervention if the patient is in a position that could be contributing to respiratory distress. However, the priority is to first assess vital signs, particularly blood pressure, to gather information about the patient's cardiovascular status.
C. Elevate the foot of the bed:
Elevating the foot of the bed may be a consideration if the dyspnea is related to conditions such as heart failure, where raising the legs can help reduce venous return and decrease the workload on the heart. However, the initial priority is to assess blood pressure to guide appropriate interventions.
D. Elevate the head of the bed:
Elevating the head of the bed may be beneficial for patients with respiratory distress to improve ventilation and oxygenation. While this intervention may be appropriate, the first action should be to assess vital signs, particularly blood pressure, to gain an overall understanding of the patient's condition.
