Community Health HESI Practice Questions

Correct Answer: B

Rationale: The correct answer is to inspect the nares and ears for skin breakdown. This is important because the nasal cannula can cause skin breakdown due to prolonged use and friction. Ensuring that the skin is intact helps prevent complications. Choice A is incorrect as oxygen therapy via a nasal cannula does not involve mist. Choice C is incorrect as lubricating the tips of the cannula is not a standard practice and may lead to complications. Choice D is incorrect because while cleanliness is important, maintaining sterile technique is not necessary for handling a nasal cannula in this context.

Correct Answer: A

Rationale: The correct first step for thermal protection of a newborn is to dry the baby thoroughly immediately after birth. This helps prevent heat loss and is crucial in maintaining the baby's body temperature. Choice B, covering the baby with a clean, dry cloth after the cord has been cut, is not the initial step as drying the baby comes first. Choice C, drying the baby thoroughly after the cord has been cut, is also not the first step. Choice D, covering the baby with a clean, dry cloth immediately after birth, is not as effective as drying the baby to prevent heat loss.

Correct Answer: D

Rationale: To excel in a health education program, a Public Health Nurse (PHN) must possess a combination of teaching-learning strategies to effectively impart knowledge, provide accurate information to ensure credibility, and communicate ideas effectively to engage and interact with the audience. Therefore, all of these skills are essential for a PHN to succeed in her health education program. Choices A, B, and C are integral components of a successful health education program, making option D the correct answer.

Correct Answer: C

Rationale: The correct answer is C: 'Dyspnea and cough.' Pulmonary embolism often presents with a sudden onset of dyspnea (difficulty breathing) and cough, which are due to the obstruction of blood flow in the pulmonary arteries. Choices A, B, and D are incorrect. Positive Homan's sign is associated with deep vein thrombosis, fever and chills are nonspecific symptoms commonly seen in infective endocarditis, and sensory impairment is not typically indicative of pulmonary embolism.

Correct Answer: B

Rationale: The correct answer is B: "Reduce acid secretion." Vagotomy is performed to reduce acid secretion by cutting the vagus nerve, which stimulates acid production. Choices A, C, and D are incorrect. A vagotomy does not increase acid secretion, promote gastric emptying, or remove the ulcerated area. It specifically aims to decrease acid production to help in the healing of peptic ulcers.
