Nursing Elites

1. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?

• A. Neurogenic shock
• B. Cardiogenic shock
• C. Hypovolemic shock
• D. Anaphylactic shock

Correct answer: D

Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.

2. The physician tells the parents of a 2-year-old that the child probably has RSV. The parents ask how the diagnosis will be confirmed. How should the nurse respond?

• A. We will swab your child's nose and send the secretions for testing.
• B. There is no specific test for RSV. The diagnosis is based on symptoms.
• C. We will send a viral culture to an outside lab for testing.
• D. There is no specific test for RSV. The diagnosis is based on symptoms.

Correct answer: A

Rationale: The correct answer is A. RSV is typically diagnosed by swabbing the nose and testing the secretions. This method helps confirm the presence of the respiratory syncytial virus. Choice B is incorrect because while symptoms are important in diagnosis, specific tests like swabbing for RSV do exist. Choice C is incorrect as sending a viral culture to an outside lab is not the primary method for diagnosing RSV. Choice D is a duplicate of choice B and is incorrect for the same reasons.

3. At which age does an infant start to recognize familiar faces and objects, such as his or her own hand?

• A. 1 month
• B. 2 months
• C. 3 months
• D. 4 months

Correct answer: C

Rationale: By 3 months, infants begin to recognize familiar faces and objects, such as their own hands. This marks the early stages of visual recognition and cognitive development.

4. The nurse notes that a child has lost 3.6 kg (8 lb) after 4 days of hospitalization for acute glomerulonephritis. What is the most likely cause of this weight loss?

• A. Poor appetite
• B. Reduction of edema
• C. Restriction to bed rest
• D. Increased potassium intake

Correct answer: B

Rationale: The weight loss is most likely due to the reduction of edema, as glomerulonephritis often causes fluid retention that resolves with treatment, leading to significant weight loss.

5. The presence of which pair of factors is a good predictor of a fluid deficit of at least 5% in an infant?

• A. Weight loss and decreased heart rate
• B. Capillary refill of less than 2 seconds and no tears
• C. Increased skin elasticity and sunken anterior fontanel
• D. Dry mucous membranes and generally ill appearance

Correct answer: D

Rationale: Dry mucous membranes and an ill appearance are good indicators of dehydration in infants, often correlating with a fluid deficit of at least 5%. Sunken fontanels and poor skin turgor are also indicative but were not options here.
