Adult Health 2 HESI Quizlet

Correct Answer: C

Rationale: The correct answer is C: 'Around the nostrils.' Constant pressure from the tubing may create skin damage to the areas of skin and bony prominences the nasal cannula will be resting on, including around the nostrils. Choice A, 'Tops of the ears,' is incorrect as the cannula does not rest on the ears. Choice B, 'Bridge of the nose,' is incorrect because the cannula typically rests under the nose. Choice D, 'Over the cheeks,' is also incorrect as the cannula does not typically rest on the cheeks.

Correct Answer: C

Rationale: Stoma output of only 40ml in the last hour may indicate a problem, such as dehydration or blockage, and should be reported immediately. A red and edematous stoma appearance could be due to inflammation, which is expected in the early postoperative period. Liquid brown drainage from the stoma is a normal finding. Mucous strings floating in the drainage are also a common occurrence postoperatively and do not typically require immediate reporting.

Correct Answer: A

Rationale: The correct answer is A - 'The patient is experiencing laryngeal stridor.' Hypocalcemia can cause laryngeal stridor, which may lead to respiratory arrest. Rapid action is required to correct the patient's calcium level to prevent a life-threatening situation. Choices B, C, and D are also symptoms of hypocalcemia, but laryngeal stridor takes precedence due to its potential to quickly progress to a critical condition.

Correct Answer: D

Rationale: The correct answer is D, Hypokalemia. Generalized weakness, muscle weakness, leg cramps, and cardiac dysrhythmias are manifestations of hypokalemia. Checking the potassium level is essential in this case. Hypocalcemia typically presents with facial muscle spasms, not the symptoms mentioned. Hypermagnesemia does not typically cause the symptoms described. It's important to note that orange juice is high in potassium and would be advisable to drink if the patient was hypokalemic. Loose stools are more commonly associated with hyperkalemia, not hypokalemia.

Correct Answer: D

Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.
