Correct Answer: A

Rationale: The correct intervention for a nursing diagnosis of risk for infection in an older incontinent client is to maintain standard precautions. The best way to reduce the risk of infection in vulnerable clients is through proper handwashing and adherence to standard precautions. Option B, initiating contact isolation measures, is excessive unless the client has a confirmed infection requiring isolation. Option C, inserting an indwelling urinary catheter, actually increases the risk of infection due to the introduction of a foreign body. Option D, instructing the client in the use of adult diapers, does not directly address the risk of infection and is not as effective as maintaining standard precautions in preventing infection transmission.

Correct Answer: A

Rationale: When the nurse rolls contaminated gloves inside-out, they are manipulating the mode of transmission in the chain of infection. The gloves, which are contaminated, act as a vehicle for transferring pathogens from the reservoir's portal of exit to a potential portal of entry. Choices B, C, and D are incorrect because the action of rolling contaminated gloves does not directly relate to the portal of entry, reservoir, or portal of exit in the chain of infection.

Correct Answer: A

Rationale: Assessing pulse characteristics is the priority in this situation due to the potential impact of lightning as a form of electrical current, which can cause irregular heart rhythms. It is crucial to evaluate the pulse rate and regularity to assess for adequate circulation and potential cardiac issues. Since the client is alert and talking, the airway is likely patent, making assessing the airway less urgent. Entrance and exit wounds and cervical spine injury assessments should follow the evaluation of pulse characteristics to ensure proper circulation and prioritize life-threatening issues first. Checking the pulse first will guide further interventions and help in determining the client's hemodynamic status.

Correct Answer: C

Rationale: The correct answer is 'Cranberry juice stops pathogens' adherence to the bladder.' Cranberry juice maintains urinary tract health by reducing the adherence of Escherichia coli bacteria to cells within the bladder. This helps prevent UTIs. Options A, B, and D are incorrect because orange juice with vitamin C, apple juice for urine acidification, and grapefruit juice for antibiotic absorption do not have the same proven effectiveness in preventing UTIs as cranberry juice does.

Correct Answer: A

Rationale: Long-term protein deficiency significantly lowers serum albumin levels. Albumin, derived from protein breakdown, is produced by the liver when adequate amino acids are available. Due to its long half-life, acute protein loss minimally affects serum albumin levels. In contrast, serum transferrin, with a shorter half-life of 8 to 10 days, decreases with acute protein deficiency and is not a reliable indicator of chronic protein malnutrition. Elevated hemoglobin levels may occur in conditions like dehydration or chronic obstructive pulmonary disease, making it an unreliable indicator of chronic protein malnutrition. High cholesterol levels are not directly linked to protein malnutrition and do not serve as a reliable indicator. Therefore, the most reliable indicator of chronic protein malnutrition among the options provided is a low serum albumin level.
