What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?

Correct Answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.

Correct Answer: B

Rationale: The most important preoperative instruction for a client with diabetes mellitus scheduled for surgery is to instruct them not to eat or drink after midnight. This instruction is crucial to maintain NPO (nothing by mouth) status before surgery, reducing the risk of aspiration during anesthesia. While taking insulin as usual (Choice A) is important, doses can be adjusted by the healthcare team. Monitoring blood glucose closely (Choice C) is essential but not as critical preoperatively. Bringing a glucose meter to the hospital (Choice D) can be helpful but is not as vital as maintaining NPO status.

Correct Answer: B

Rationale: The correct first action for the nurse is to assess the nature and intensity of the pain. This initial assessment is crucial in determining the underlying cause of the pain, whether it is related to the chemotherapy or another issue. Understanding the pain's characteristics will guide the nurse in implementing appropriate interventions and seeking timely medical assistance if needed. Administering pain medication without a thorough assessment may mask important symptoms and delay necessary treatment. Encouraging rest and hot pack application may be appropriate interventions but should come after assessing the pain. Notifying the physician immediately can be important but should follow the initial assessment to provide comprehensive information to the healthcare provider.

Correct Answer: D

Rationale: The most crucial aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is essential to detect early signs of complications such as ischemia or infection. Changing the colostomy bag daily is important but not as critical as assessing the stoma for complications. Irrigating the colostomy daily is not a standard recommendation and should be performed based on healthcare provider's instructions. While avoiding high-fiber foods may be beneficial for some individuals with a colostomy, it is not the most important aspect of care compared to monitoring the stoma for complications.

Correct Answer: C

Rationale: Clients with limited mobility are at the highest risk for developing pressure ulcers due to prolonged pressure on specific areas of the body. This constant pressure can lead to tissue damage and ultimately result in pressure ulcers. While age and medical conditions such as diabetes and a history of stroke can contribute to the risk of pressure ulcers, limited mobility is the most significant factor as it directly affects the ability to shift positions and relieve pressure on vulnerable areas of the body. Therefore, the 65-year-old client with limited mobility is at the highest risk compared to the other clients. The 50-year-old client with a fractured femur may have limited mobility due to the injury, but it is temporary and may not be as prolonged as chronic limited mobility. The 30-year-old client with diabetes mellitus and the 70-year-old client with a history of stroke are at risk for developing pressure ulcers, but their conditions do not directly impact their ability to shift positions and alleviate pressure like limited mobility does.

Correct Answer: A

Rationale: Administering a bronchodilator as prescribed is the priority nursing intervention for a client experiencing wheezing and shortness of breath due to asthma. Bronchodilators help relieve bronchoconstriction, allowing better airflow and improving breathing. Encouraging the client to drink fluids may be beneficial in certain situations, but it is not the priority when the client is in respiratory distress. Placing the client in an upright position, not supine, can facilitate easier breathing by allowing the chest to expand fully. While assessing the client's peak flow rate is important in asthma management, in this acute situation, the priority is to provide immediate relief by administering the bronchodilator.

Correct Answer: B

Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.

Correct Answer: B

Rationale: Providing frequent oral care is crucial when a client is NPO to ensure comfort and prevent drying of the oral mucosa. In this situation, the priority is maintaining oral hygiene to prevent complications such as oral mucosa breakdown. Monitoring bowel sounds may be important in assessing bowel activity, but it is not the priority when the client is NPO due to a small bowel obstruction. Encouraging ambulation can be beneficial for other conditions, but in this case, oral care takes precedence. Measuring abdominal girth is more relevant for assessing abdominal distention, which is not the priority when the client is NPO. Therefore, the most important nursing intervention is to provide frequent oral care.

Correct Answer: D

Rationale: The correct answer is D, Peritoneum. The peritoneum is the membrane that lines the abdominal cavity, providing support to abdominal organs and serving as a conduit for their blood vessels. Choices A, B, and C are incorrect. The perineum refers to the area between the anus and the external genitalia, the pericardium is the membrane enclosing the heart, and the pleura is the membrane surrounding the lungs.
