HESI Fundamentals Practice Questions
1. Prior to a client being transported for a chest x-ray, what should a healthcare professional do first?
- A. Identify the client using two identifiers
- B. Confirm the client's fasting status
- C. Check the client's allergies to contrast media
- D. Explain the procedure to the client
Correct answer: A
Rationale: Identifying the client using two identifiers is the crucial first step to ensure correct patient identification before any procedure. This process helps prevent errors and ensures that the right procedure is performed on the right patient. Confirming the client's identity is the top priority before addressing other aspects such as fasting status, allergies, or explaining the procedure. While confirming fasting status and checking for allergies are important, they are secondary to confirming the client's identity. Explaining the procedure to the client is also essential but should occur after ensuring proper identification.
2. A client is prescribed an antacid for the treatment of peptic ulcer disease. What is the action of this medication that is effective in treating the client's ulcer?
- A. Decrease in the production of gastric secretions
- B. Production of an adherent barrier over the ulcer
- C. Maintenance of a gastric pH of 3.5 or above
- D. Decrease in the gastric motor activity
Correct answer: C
Rationale: The correct answer is C. Antacids work by neutralizing gastric acids and maintaining a gastric pH of 3.5 or above. This pH level is crucial to prevent the activation of pepsinogen, a precursor to pepsin, which can further damage the ulcer. Choice A is incorrect because antacids do not directly decrease the production of gastric secretions; they neutralize existing acid. Choice B is incorrect as antacids do not form a physical barrier over the ulcer but rather neutralize the acid around it. Choice D is also incorrect as antacids do not affect gastric motor activity but focus on reducing acidity in the stomach.
3. A male client is brought to the emergency department by a police officer, who reports the client was disturbing the peace by running naked in the street, striking out at others, and smashing car windows. Which behaviors should the client demonstrate to determine if he should be evaluated for involuntary commitment?
- A. Threats to kill his friend.
- B. Disruptive behaviors in a community setting.
- C. Hears voices telling him to kill himself.
- D. Reports he has not needed a bath in 4 months.
Correct answer: D
Rationale: The client's dangerous and disruptive behaviors, along with auditory hallucinations of self-harm, suggest a need for involuntary commitment for his safety and that of others. Involuntary commitment may be warranted based on the client's poor hygiene and self-neglect, as it indicates an inability to care for himself, which can pose a risk to his well-being.
4. A client with generalized anxiety disorder (GAD) is prescribed buspirone (BuSpar). The nurse should include which information in the client's discharge teaching?
- A. This medication can cause physical dependence.
- B. It may take 2 to 4 weeks before you notice improvement.
- C. Avoid alcohol while taking this medication.
- D. You may experience sedation as a side effect.
Correct answer: B
Rationale: Corrected Rationale: Buspirone takes time to become fully effective, so the client should be informed to expect a gradual improvement in anxiety symptoms. Choice A is incorrect because buspirone is not associated with physical dependence. Choice C is not directly related to buspirone but is generally a good practice when taking any medication. Choice D is less common with buspirone compared to other anxiety medications.
5. What is the primary function of neutrophils?
- A. Heparin secretion
- B. Transport oxygen
- C. Phagocytotic action
- D. Antibody formation
Correct answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
