Correct Answer: D

Rationale: After surgery, some clients may experience a laryngospasm during emergence from anesthesia. A laryngospasm can lead to the closure of the laryngeal opening due to spasm of the vocal cords. In this scenario, the client's symptoms of wheezing and throat grasping are indicative of a laryngospasm rather than choking on the tube, anxiety, or a normal response from anesthesia. The nurse should act promptly to open the airway to aid breathing and consider administering muscle relaxants as necessary.

Correct Answer: D

Rationale: When assessing blood pressure by palpation, it is important to note that only the systolic blood pressure can be determined accurately using this method. Diastolic blood pressure cannot be reliably assessed through palpation. The palpation technique is particularly useful in situations where traditional blood pressure measurement methods are challenging, such as in infants, small children, or individuals with low blood pressure that is difficult to hear. Hypertension, a common condition characterized by elevated blood pressure, is typically assessed using auscultation rather than palpation. Therefore, the correct statement is that only the systolic blood pressure can be assessed through palpation.

Correct Answer: C

Rationale: The correct answer is a 58-year-old female with near-syncope. Orthostatic hypotension is a drop in blood pressure of greater than 20 mmHg systolic when moving from a sitting or lying position to standing. Patients at higher risk include those with syncope or near-syncope, symptomatic hypovolemia, and those prone to falls. The other choices are less likely to present with orthostatic hypotension. A spinal injury, altered mental status, and acute deep vein thrombosis are not directly associated with the immediate need for orthostatic hypotension measurement.

Correct Answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

Correct Answer: D

Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.
