Nursing Elites

1. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?

• A. The life span of RBC is 45 days
• B. The life span of RBC is 60 days
• C. The life span of RBC is 90 days
• D. The life span of RBC is 120 days

Correct answer: D

Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.

2. The nurse develops a plan of care to prevent aspiration in a high-risk patient. Which nursing action will be most effective?

• A. Turn and reposition immobile patients at least every 2 hours.
• B. Place patients with altered consciousness in side-lying positions.
• C. Monitor for respiratory symptoms in immunosuppressed patients.
• D. Insert nasogastric tube for feedings in patients with swallowing problems.

Correct answer: B

Rationale: To prevent aspiration in a high-risk patient, the most effective nursing action is to place patients with altered consciousness in side-lying positions. This position helps decrease the risk of aspiration as it prevents pooling of secretions and facilitates drainage. Turning and repositioning immobile patients every 2 hours is essential for preventing pressure ulcers and improving circulation but does not directly address the risk of aspiration. Monitoring respiratory symptoms in immunosuppressed patients is crucial to detect pneumonia early, but it does not directly prevent aspiration. Inserting a nasogastric tube for feedings in patients with swallowing problems may be necessary for nutritional support but does not address the risk of aspiration directly. Patients at high risk for aspiration include those with altered consciousness, difficulty swallowing, and those with nasogastric intubation, among others. Placing patients with altered consciousness in a side-lying position is a key intervention to reduce the risk of aspiration in this population. Other high-risk groups for aspiration include those who are seriously ill, have poor dentition, or are on acid-reducing medications.

3. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)

• A. Age
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: D

Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.

4. A child is suspected of suffering from intussusception. The nurse should be alert to which clinical manifestation of this condition?

• A. Tender, distended abdomen
• B. Presence of fecal incontinence
• C. Incomplete development of the anus
• D. Infrequent and difficult passage of dry stools

Correct answer: A

Rationale: Intussusception is an invagination of a section of the intestine into the distal bowel, and it is the most common cause of bowel obstruction in children aged 3 months to 6 years. A tender, distended abdomen is a typical clinical manifestation of intussusception. The presence of fecal incontinence is not a characteristic presentation of intussusception; it describes encopresis, which generally affects preschool and school-aged children but is not specific to intussusception. Incomplete development of the anus describes imperforate anus, a disorder diagnosed in the neonatal period, not intussusception. The infrequent and difficult passage of dry stools is characteristic of constipation, a common issue in children that can occur at any age, although it often peaks at 2 to 3 years old.

5. Mr. L was working in his garage at home and had an accident with a power saw. He is brought into the emergency department by a neighbor with a traumatic hand amputation. What is the first action of the nurse?

• A. Place a tourniquet at the level of the elbow
• B. Apply direct pressure to the injury
• C. Administer a bolus of 0.9% Normal Saline
• D. Elevate the injured extremity on a pillow

Correct answer: B

Rationale: The correct first action for the nurse in this scenario is to apply direct pressure to the injury. When a client presents with traumatic hand amputation causing excessive bleeding, the immediate goal is to control the bleeding. Applying direct pressure with a sterile dressing helps to stem the flow of blood and stabilize the patient. Placing a tourniquet at the level of the elbow should be avoided initially as it may lead to further complications such as tissue damage. Administering a bolus of 0.9% Normal Saline is not the priority in this situation where hemorrhage control is crucial. Elevating the injured extremity on a pillow does not address the primary concern of controlling the bleeding and stabilizing the patient.
