1. The client is a chronic carrier of infection. To prevent the spread of the infection to other clients or healthcare providers, the nurse emphasizes interventions that do which of the following? (Berman & Snyder, 2012, p. 713)

A. Eliminate the reservoir
B. Block the portal of exit from the reservoir
C. Block the portal of entry into the host
D. Decrease the susceptibility of the host

Correct answer: Block the portal of exit from the reservoir

Rationale: To prevent the spread of infection from a chronic carrier, the nurse should focus on blocking the portal of exit from the reservoir, which is the carrier person. By preventing the movement of the organism from the reservoir, the infection can be contained. Eliminating the reservoir is not feasible in this case as the carrier is a chronic carrier. Blocking the portal of entry into the host or decreasing the susceptibility of the host would only impact individual prevention and not the spread from the carrier to others.

2. What is the proper personal protective equipment necessary for collecting a sputum specimen?

A. Gloves and face mask
B. Level Three Biocontainment uniforms
C. Eye protection and shoe covers
D. Splash shield and face mask

Correct answer: Gloves and face mask

Rationale: When collecting a sputum specimen, it is crucial to protect against potential airborne droplets that may spread disease. The best personal protective equipment for this task includes gloves and a face mask. Gloves help prevent the spread of contaminants through hand contact, while a face mask protects the respiratory tract from inhaling infectious agents. Choice B, Level Three Biocontainment uniforms, is excessive and unnecessary for routine sputum specimen collection. Choice C, eye protection and shoe covers, does not address the specific risks associated with sputum collection. Choice D, splash shield and face mask, provides additional protection that is not typically required for sputum specimen collection, making it less appropriate than gloves and a face mask.

3. The abbreviation ac is defined as _____________.

A. before the meal
B. with the meal
C. after the meal
D. ante cibum

Correct answer: before the meal

Rationale: The correct answer is 'before the meal.' The abbreviation 'ac' is derived from the Latin term 'ante cibum,' which translates to 'before a meal.' Choices B, C, and D are incorrect because 'ac' does not refer to 'with the meal,' 'after the meal,' or 'ante corpis.' It specifically denotes something occurring before a meal, making option A the correct choice in this context.

4. Who should be members of a patient care conference?

A. Doctors, nurses, and nursing assistants since they are healthcare providers
B. Doctors, nurses, and the patient and/or the family members
C. ALL members of the healthcare team
D. ALL members of the healthcare team and the patient/resident

Correct answer: ALL members of the healthcare team and the patient/resident

Rationale: In a patient care conference, it is essential to have all members of the healthcare team present to ensure comprehensive and coordinated care. Including the patient or resident, along with their family members if desired, is crucial as they are the focus of care. Choice A is incorrect because it excludes other important members of the healthcare team. Choice B is partially correct as it includes the patient and/or family members but does not encompass the entire healthcare team. Choice C is too broad and does not specifically address the inclusion of the patient or resident. The correct answer, Choice D, includes all healthcare team members and the patient/resident, ensuring a holistic approach to patient-centered care.

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

A. Crystal violet
B. Methyl alcohol
C. Iodine
D. Safranin

Correct answer: Iodine

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.
