HESI Test Bank Medical Surgical Nursing

Correct Answer: A

Rationale: The correct answer is A: Neutrophil count. Neutrophil count helps assess for infection, which is indicated by the redness, tenderness, and swelling of the wound. Elevated neutrophil count is a common sign of bacterial infection. Hematocrit (choice B) measures the proportion of blood volume that is occupied by red blood cells and is not directly related to wound infection. Blood pH (choice C) and serum potassium and sodium (choice D) are important for assessing acid-base balance and electrolyte levels but are not the primary indicators of wound infection.

Correct Answer: B

Rationale: The child with LTB should be placed in the mist tent with 30% oxygen. Restlessness is caused by poor oxygenation. The child should not be taken out of the oxygenated tent. While the mother could be asked to help comfort the child, and the health care provider may be notified, the priority is to set the oxygen at the correct level.

Correct Answer: A

Rationale: The correct answer is A: Abduction. The use of the Pavlik harness is to maintain the hips in abduction for 4 to 6 months to treat developmental hip dysplasia. This position helps in stabilizing the hip joint and promoting proper growth and development. Choices B, C, and D are incorrect because the Pavlik harness specifically aims to hold the child's femurs in abduction, not adduction, flexion, or extension.

Correct Answer: C

Rationale: The correct approach when performing postural drainage on a client with COPD is to assist the patient into a position that allows gravity to help move secretions. This position helps drain secretions from specific segments of the lungs. Obtaining arterial blood gases (Choice A) is not directly related to postural drainage. While the client may be placed in multiple positions during postural drainage, the key is to position them to facilitate the movement of secretions, not just any five positions as mentioned in Choice B. Encouraging deep breathing (Choice D) is a good nursing intervention for overall respiratory health but is not specifically related to the technique of postural drainage.

Correct Answer: C

Rationale: A child with an IQ of 45 is classified as 'Trainable' in the context of cognitive impairment levels. This category is determined by an IQ range of 35 to 55. Choice A ('Within the normal low range') is incorrect as an IQ of 45 falls within the range associated with the 'Trainable' level, not the 'Normal low range.' Choice B ('Educable') is incorrect because this classification typically corresponds to individuals with slightly higher IQs that allow for academic progress with support. Choice D ('Severe') is incorrect as it does not align with the IQ level of 45, which falls within the 'Trainable' category.
