HESI LPN
Adult Health 2 Final Exam
1. The nurse is assessing a client with a suspected pulmonary embolism (PE). Which symptom is most indicative of this condition?
- A. Bilateral leg swelling.
- B. Sudden onset of chest pain.
- C. Gradual onset of dyspnea.
- D. Decreased breath sounds on auscultation.
Correct answer: C
Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.
2. 4 hours after administration of 20U of regular insulin, the client becomes shaky and diaphoretic. What action should the nurse take?
- A. Encourage the client to eat crackers and milk
- B. Administer a PRN dose of 10U of regular insulin
- C. Give the client crackers and milk
- D. Record the client's reaction in the diabetic flow sheet
Correct answer: C
Rationale: The correct action for the nurse to take when a client becomes shaky and diaphoretic after insulin administration, indicating hypoglycemia, is to provide the client with carbohydrates like crackers and milk. Carbohydrates help raise blood glucose levels quickly. Encouraging the client to eat crackers and milk (Choice A) is the appropriate immediate action to address the hypoglycemia. Administering more insulin (Choice B) would worsen hypoglycemia, and recording the reaction (Choice D) is important but not the immediate action needed to treat the hypoglycemia.
3. A client complains of pain at the IV site. Upon assessment, the nurse notes the site is warm, red, and swollen. What is the most likely cause of these findings?
- A. Phlebitis
- B. Infiltration
- C. Allergic reaction
- D. Fluid overload
Correct answer: A
Rationale: The correct answer is A, Phlebitis. Phlebitis is the inflammation of a vein, often caused by irritation from an IV catheter, resulting in warmth, redness, and swelling at the site. Infiltration (choice B) refers to the leaking of IV fluids into the surrounding tissues, causing swelling and pallor, not redness and warmth like in the scenario described. An allergic reaction (choice C) would present with itching, hives, or anaphylaxis, rather than localized warmth, redness, and swelling. Fluid overload (choice D) typically manifests as generalized edema, shortness of breath, and weight gain, not localized symptoms at the IV site.
4. During a bed bath, the nurse observes that a client's IV site is red and swollen. What should the nurse do first?
- A. Discontinue the IV under physician's guidance
- B. Apply a warm compress to the site
- C. Notify the physician
- D. Document the appearance of the site and continue the bath
Correct answer: C
Rationale: The correct first action when a nurse observes a red and swollen IV site during a bed bath is to notify the physician. This is crucial because prompt reporting allows for immediate intervention to prevent further complications. Discontinuing the IV (Choice A) should only be done under the physician's guidance to avoid any adverse effects and ensure proper care. Applying a warm compress (Choice B) may not address the underlying issue and could potentially worsen the situation if the cause is an infection or infiltration. Documenting the site's appearance and continuing the bath (Choice D) without immediate action might delay necessary treatment, leading to potential complications.
5. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?
- A. Filtration
- B. Diffusion
- C. Osmosis
- D. Active transport
Correct answer: C
Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
