A nurse is preparing a patient for a sigmoidoscopy.
In which of the following positions should the nurse place the patient?
Knee-chest
Prone
Orthopneic
Trendelenburg .
The Correct Answer is A
A sigmoidoscopy is a procedure used to examine the lower part of the colon (sigmoid colon and rectum). The knee-chest position allows for better visualization of the sigmoid colon by straightening the rectosigmoid junction.
Choice B rationale
The prone position is not typically used for sigmoidoscopy. This position does not provide optimal visualization of the sigmoid colon.
Choice C rationale
The orthopneic position, which involves sitting up and leaning forward, is not used for sigmoidoscopy.
Choice D rationale
The Trendelenburg position, which involves lying flat with the feet elevated higher than the head, is not used for sigmoidoscopy.

Correct Answer is B
Explanation
Choice A rationale
Applying mystatin cream to the blistered areas is not typically recommended for herpes zoster lesions. Mystatin is an antifungal medication, and herpes zoster is caused by a virus, not a fungus.
Choice B rationale
Implementing contact precautions is recommended for patients with widespread herpes zoster lesions. This helps to prevent the spread of the virus to other people.
Choice C rationale
Using warm compresses on the crusted lesions is not typically recommended. While warm compresses can help with some skin conditions, they are not usually part of the care plan for herpes zoster.
Choice D rationale
Administering the shingles vaccine is not typically done once a patient already has widespread herpes zoster lesions. The vaccine is used to prevent shingles, not to treat active cases.
Correct Answer is C
Explanation
Choice A rationale
Unscrewing the pins to clean the pin sites is not recommended. This could lead to infection and disrupt the traction.
Choice B rationale
Loosening the rope knots holding the weights for 30 minutes if the patient reports pain is not recommended. The weights provide the necessary force to align and immobilize the body part and should not be removed.
Choice C rationale
Ensuring that at least 4.5 kg (10 lb) of weight is applied to the patient’s traction is a correct action. The amount of weight applied must be sufficient to provide the necessary force for alignment.
Choice D rationale
Removing the weights while turning the patient in bed is not recommended. The weights must remain in place to maintain the therapeutic effect of the traction.
