Medical Surgical Assignment Exam HESI

Correct Answer: C

Rationale: The correct answer is C, Normal sinus rhythm. Normal sinus rhythm is characterized by a regular rhythm, normal P waves, and a consistent PR interval. In this context, the strip likely shows a normal ECG pattern with these characteristics, indicating a healthy heart rhythm. Choices A, B, and D are incorrect. Atrial fibrillation would show an irregularly irregular rhythm with no discernible P waves. Ventricular tachycardia would display wide QRS complexes and a fast heart rate. Second-degree heart block would exhibit intermittent dropped QRS complexes.

Correct Answer: D

Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.

Correct Answer: B

Rationale: Placing the child on the affected side after a myringotomy facilitates ear drainage. This position helps prevent accumulation of fluids in the ear canal, aiding in the healing process. Placing the child in the supine position (Choice A) or on the unaffected side (Choice C) may not be as effective in promoting drainage. The Trendelenburg's position (Choice D) with the head lower than the body is used for conditions requiring increased venous return, not for post-myringotomy care.

Correct Answer: D

Rationale: Elevating the head of the bed 60 to 90 degrees is the correct intervention to facilitate proper placement of the NG tube. This position helps to use gravity to guide the tube smoothly into the gastrointestinal tract. Soaking the NG tube in warm water (Choice A) is not necessary for proper placement. Inserting the tube with the client's head tilted back (Choice B) can cause discomfort and may lead to improper placement. Applying suction while inserting the tube (Choice C) is not recommended as it can cause trauma to the nasal passages and esophagus.

Correct Answer: C

Rationale: Evaluating the client's ability to swallow is the priority intervention in this scenario. Pontine myelinolysis can affect neurological functions, including swallowing ability, putting the client at risk for aspiration. Assessing the client's ability to swallow will help prevent complications such as aspiration pneumonia. Reorienting the client to the room, placing an eye patch, or performing range of motion exercises are not as critical as ensuring the client can safely swallow.
