1. Which of the following is a fat-soluble vitamin?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin B-6
- D. Riboflavin
Correct answer: B
Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K. Choice A, Vitamin C, is water-soluble, not fat-soluble. Choice C, Vitamin B-6, and Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.
2. Efforts by healthcare facilities to reduce the incidence of hospital-acquired infections (HAIs) include an awareness of which of the following?
- A. The CDC requires all states to report HAI rates from each hospital.
- B. Ensure that the restraints are tied to the side rails.
- C. The gastrointestinal tract is a common site for HAIs.
- D. Joint Commission considers death or serious injury from HAIs a sentinel event.
Correct answer: D
Rationale: Efforts to reduce hospital-acquired infections (HAIs) involve being aware that the Joint Commission considers death or serious injury resulting from HAIs a sentinel event, which must be reported. While more than 20 states require reporting of HAI rates to the CDC, it is not a nationwide CDC requirement. The gastrointestinal tract is not a specific common site for HAIs; rather, bacteria are the primary cause. Ensuring restraints are properly secured is important for patient safety but not directly related to reducing HAIs.
3. A client has died approximately one hour ago. The nurse notes that the client's temperature has decreased in the last hour since their death. Which of the following processes explains this phenomenon?
- A. Rigor mortis
- B. Postmortem decomposition
- C. Algor mortis
- D. Livor mortis
Correct answer: C
Rationale: Algor mortis occurs after death when the body's circulation stops, and the client's temperature begins to fall. The client's temperature will drop by approximately 1.8 degrees per hour until it reaches room temperature. During algor mortis, the client's skin gradually loses its elasticity. Rigor mortis refers to the stiffening of the body after death due to chemical changes in the muscles. Postmortem decomposition is the breakdown of tissues after death. Livor mortis is the pooling of blood in the dependent parts of the body, causing a purple-red discoloration.
4. You are working the 8 am to 4 pm shift. You begin to vomit at 3 pm and you do not think that you are able to continue working. You decide to immediately go home without notifying your RN supervisor. You have ________________.
- A. enough sick time, so this is not a problem.
- B. finished all your work, so this is not a problem.
- C. seriously abandoned the patients.
- D. seriously abused and neglected the patients.
Correct answer: D
Rationale: Patient abandonment is a serious violation that can lead to disciplinary action and immediate termination of employment. It is defined as leaving patients without proper consent from the supervisor. In this scenario, leaving work without notifying the RN supervisor and potentially leaving patients unattended is considered patient abandonment, as it compromises patient safety and care. Choices A and B are incorrect because having sick time or finishing work does not justify leaving without proper protocol. Choice D is incorrect as the scenario does not indicate abuse or neglect towards the patients.
5. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
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.
