HESI Practice Test for Fundamentals

Correct Answer: A

Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).

Correct Answer: A

Rationale: In a client with a history of asthma experiencing difficulty breathing and wheezing, the priority nursing action is to administer a bronchodilator. This intervention helps relieve bronchospasm and improve the client's breathing. Obtaining a peak flow reading can provide additional information but is not the immediate priority in this situation. Providing supplemental oxygen may be needed but addressing the bronchospasm with a bronchodilator takes precedence. Assessing the client's respiratory rate is important but not as urgent as administering a bronchodilator to address the breathing difficulty.

Correct Answer: A

Rationale: The correct answer is A: Chicken breast. In chronic kidney disease, a low-protein diet is often recommended to reduce the workload on the kidneys. Chicken breast is a high-protein food that should be limited in such diets to help manage the progression of kidney disease. Choices B, C, and D are low in protein and are generally suitable for individuals following a low-protein diet. Apples, rice, and bananas can be included in moderation as part of a balanced diet for individuals with chronic kidney disease.

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: D

Rationale: The correct answer is D: Abdominal mass and weakness. In neuroblastoma, the most common presenting signs are related to the mass effect of the tumor, leading to an abdominal mass and symptoms of weakness. Lymphedema and nerve palsy (Choice A) are not typically associated with neuroblastoma. Hearing loss and ataxia (Choice B) are more indicative of other conditions like neurofibromatosis or brain tumors. Headaches and vomiting (Choice C) are more commonly seen in conditions such as brain tumors or increased intracranial pressure, but they are not specific to neuroblastoma.
