HESI PN Exit Exam

Correct Answer: A

Rationale: The correct answer is to recommend increasing the intake of dried peaches and apricots. A serum potassium level of 3.0 mEq/L is considered low. Increasing the intake of potassium-rich foods can help raise the serum potassium level, preventing complications such as muscle weakness and cardiac arrhythmias. Choice B, reducing intake of red meats, is incorrect because red meats are not specifically related to potassium levels. Choice C, encouraging the use of a soft toothbrush, is unrelated to addressing low potassium levels. Choice D, forcing fluid intake to 1500 mL daily, is not the appropriate intervention for low serum potassium; instead, increasing potassium-rich foods is more beneficial.

Correct Answer: A

Rationale: Choice A is correct because the family may interpret the client's hallucinations through their cultural lens, potentially viewing them as normal or spiritually significant. Understanding and acknowledging the cultural context is essential for providing culturally sensitive care. Choices B, C, and D are incorrect because while talking circles and seeking guidance from a medicine man may be culturally relevant interventions in some contexts, the priority in this situation is to recognize and respect the family's perspective on the client's hallucinations.

Correct Answer: D

Rationale: Kegel exercises involve the pelvic floor muscles. These muscles help strengthen the muscles controlling urination, potentially reducing symptoms of urinary incontinence. Pectoral muscles (Choice A), responsible for movement of the shoulders and arms, are not involved in Kegel exercises. Buttock muscles (Choice B) are primarily responsible for hip movement and stability, not related to Kegel exercises. Abdominal muscles (Choice C) support the core and trunk but are not the focus of Kegel exercises.

Correct Answer: C

Rationale: When a patient on anticoagulant therapy experiences sudden, severe back pain, the priority nursing action is to assess for signs of internal bleeding. Severe back pain in this context could be indicative of internal bleeding, such as a retroperitoneal bleed, which is a critical condition requiring immediate attention. Administering pain medication or applying a cold compress may mask or delay the identification of a potentially life-threatening situation. Repositioning the patient for comfort is not the priority when internal bleeding needs to be ruled out.

Correct Answer: A

Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.
