Nursing Elites

1. The mitral valve is synonymous with the term:

• A. Left ventricle
• B. Right atrium
• C. Bicuspid valve
• D. Tricuspid valve

Correct answer: C

Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.

2. Which nursing intervention is most appropriate to reduce environmental stimuli that may cause discomfort for a client?

• A. Loosen pressure dressings on wounds
• B. Use assistance to lift a client in bed
• C. Check temperature of water used in a sponge bath
• D. Position the client in a prone position

Correct answer: C

Rationale: To reduce environmental stimuli that may cause discomfort for a client, nurses can implement various interventions. Checking the temperature of the water used in a sponge bath is crucial to prevent burns from water that is too hot or discomfort from water that is too cold. This intervention addresses a common source of discomfort for clients during personal care. Loosening pressure dressings on wounds, although important for wound care, does not directly address environmental stimuli. Using assistance to lift a client in bed is about proper positioning and preventing injury rather than reducing environmental stimuli. Positioning the client prone is not a suitable intervention for reducing discomfort caused by environmental stimuli.

3. The nurse is assessing an 8-year-old child whose growth rate measures below the third percentile for a child his age. He appears significantly younger than his stated age and is chubby with infantile facial features. Which condition does this child likely have?

• A. Acromegaly
• B. Marfan syndrome
• C. Hypopituitary dwarfism
• D. Achondroplastic dwarfism

Correct answer: C

Rationale: Hypopituitary dwarfism is caused by a deficiency in growth hormone in childhood and results in a retardation of growth below the third percentile, delayed puberty, and other problems. The child's appearance fits this description. Achondroplastic dwarfism is a genetic disorder resulting in characteristic deformities; Marfan syndrome is an inherited connective tissue disorder characterized by a tall, thin stature and other features. Acromegaly is the result of excessive secretion of growth hormone in adulthood which causes overgrowth of bone in the face, head, hands, and feet.

4. The nurse is assessing children in a pediatric clinic. Which statement is true regarding the measurement of blood pressure in children?

• A. Blood pressure guidelines for children are based on age.
• B. Phase II Korotkoff sounds are the best indicator of systolic blood pressure in children.
• C. Using a Doppler device is recommended for accurate blood pressure measurements until adolescence.
• D. The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children.

Correct answer: D

Rationale: The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults. Blood pressure guidelines for children are based on more than just age, but also sex and height. Phase I Korotkoff, not Phase II, is the best indicator of systolic blood pressure. The true statement regarding the measurement of blood pressure in children is that the disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults.

5. When is a physician likely to assess turgor?

• A. When iron deficiency is suspected.
• B. When heart and lung issues are suspected.
• C. When dehydration is suspected.
• D. None of the above.

Correct answer: C

Rationale: Skin turgor is assessed when dehydration is suspected. To evaluate skin turgor, a physician pinches the skin and observes how quickly it returns to its normal position. If the skin stays folded for an extended period, it indicates dehydration. Assessing turgor helps determine a patient's hydration status. Choice A is incorrect because skin turgor is not used to assess iron deficiency. Choice B is incorrect as turgor is not related to heart and lung issues, but rather hydration status. Choice D is incorrect as turgor assessment is relevant when dehydration is suspected.
