HESI Practice Test for Fundamentals

Correct Answer: D

Rationale: The correct answer is D. Removing the mobile when the baby starts to push up prevents choking hazards as infants can reach and grab objects posing a risk of choking. Choice A is unsafe as setting the water heater at 130�F can scald a child. Choice B is incorrect because even when a baby can sit up, they still require close supervision in the bathtub. Choice C is unsafe as current guidelines recommend placing babies on their backs to sleep to reduce the risk of sudden infant death syndrome (SIDS). Therefore, choices A, B, and C are incorrect or unsafe practices for infant care.

Correct Answer: B

Rationale: The correct answer is B, which is low-molecular-weight heparin doses. After hip replacement surgery, patients are at risk of developing deep vein thrombosis (DVT) due to immobility. Heparin and low-molecular-weight heparin are commonly used for prophylaxis against DVT. Monitoring for hemorrhage is crucial when administering anticoagulants. Choices A, C, and D are not directly related to monitoring for hemorrhage in this scenario. Thick, tenacious pulmonary secretions (Choice A) may indicate respiratory issues, SCDs (Choice C) help prevent DVT but do not directly relate to hemorrhage monitoring, and elastic stockings (TED hose) (Choice D) are used for DVT prophylaxis but do not alert to hemorrhage.

Correct Answer: A

Rationale: Lorazepam (Ativan) is the most appropriate preoperative medication for a client with severe anxiety. Lorazepam belongs to the benzodiazepine class and is commonly used to manage anxiety before surgical procedures due to its anxiolytic properties. Morphine sulfate and Meperidine (Demerol) are opioid analgesics, not typically indicated for preoperative anxiety. Promethazine (Phenergan) is an antihistamine used for nausea and vomiting, not anxiety management.

Correct Answer: D

Rationale: The correct answer is 'Hernias.' Abdominal distention with a midline protrusion, taut skin, and no involvement of the flanks is characteristic of hernias. Hernias are caused by a weakness in the abdominal wall, allowing organs or tissues to protrude through. Fluid accumulation (ascites) typically presents with a more generalized distention, while fat accumulation may cause more diffuse distension rather than a focal midline protrusion. Flatus, or gas, would not typically present with a visible midline protrusion and taut skin like hernias.

Correct Answer: D

Rationale: The correct answer is D. Removing the mobile when the baby starts to push up prevents choking hazards as infants can reach and grab objects posing a risk of choking. Choice A is unsafe as setting the water heater at 130�F can scald a child. Choice B is incorrect because even when a baby can sit up, they still require close supervision in the bathtub. Choice C is unsafe as current guidelines recommend placing babies on their backs to sleep to reduce the risk of sudden infant death syndrome (SIDS). Therefore, choices A, B, and C are incorrect or unsafe practices for infant care.
