1. In the Gram Stain procedure, which component acts as the mordant?

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. A nurse is completing an incident report about a medication error that she made when she accidentally administered too much insulin to a diabetic client. All of the following are components of this documentation EXCEPT:

Correct answer: A

Rationale: When completing an incident report for a medication error, it is essential to include factual information such as the type of drug involved, the amount administered, and any adverse effects on the client. However, stating the reason for administering the wrong dose should be avoided in documentation. The focus should be on reporting what happened rather than assigning blame or admitting fault. This approach helps in ensuring a thorough and accurate account of the medication error without introducing subjective elements that could complicate the investigation or resolution process. Therefore, the correct answer is 'The reason for administering the wrong dose.' Choices A, B, and D are vital components of incident report documentation, providing crucial details that help in understanding the error and its impact on the client.

3. A client is undergoing range of motion exercises, and the nurse moves the leg in a pattern of circumduction. Which movement is the nurse performing?

Correct answer: C

Rationale: Circumduction involves moving a limb in a circular pattern. In this scenario, the nurse is performing circumduction by moving the leg in a circular motion, engaging the muscles of the gluteus maximus and gluteus medius. Choice A, 'Bending the leg at the knee,' is incorrect as it describes flexion and extension movements. Choice B, 'Turning the foot inward and outward,' refers to inversion and eversion movements of the foot, not circumduction. Choice D, 'Moving the leg forward and up,' describes flexion and abduction movements, not circumduction.

4. Which of the following would be most important for the nurse to keep in mind regarding the use of side rails for a confused patient?

Correct answer: A

Rationale: When considering the use of side rails for a confused patient, it is crucial for the nurse to understand that individuals of small stature are at a higher risk for injury from entrapment. Studies have shown that people of small stature are more likely to slip through or between the side rails, making them vulnerable to harm. It is essential to prioritize patient safety and avoid potential risks associated with entrapment. Conversely, a history of previous falls from a bed with raised side rails is significant as it indicates a heightened risk for future serious incidents. The desire to prevent a patient from wandering alone does not justify the use of side rails; instead, alternative measures should be creatively employed to respect the patient's dignity and avoid more serious fall-related injuries.

5. Which of the following is the correct sequence for removing personal protective equipment?

Correct answer: C

Rationale: The correct sequence for removing personal protective equipment is crucial to prevent contamination. When exiting a surgical or aseptic situation, the proper sequence is to first remove gloves, followed by the gown, mask, and finally shoe covers. This order ensures that potentially contaminated items are removed first, minimizing the risk of exposure. Choice A, 'Remove gown, gloves, shoe covers, mask,' is incorrect as gloves should be removed before the gown. Choice B, 'Remove mask, gloves, gown, shoe covers,' is incorrect as gloves should be removed first. Choice D, 'Remove shoe covers, mask, gloves, gown,' is incorrect as gloves should be the first item removed to prevent contamination.
