HESI Practice Test for Fundamentals Questions
Question 1 of 9
The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?
Correct Answer: B
Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.
Question 2 of 9
When assessing the skin of an immobilized patient, what should the nurse do?
Correct Answer: C
Rationale: When assessing the skin of an immobilized patient, it is essential to use a standardized tool like the Braden Scale. This tool helps in systematically evaluating the patient's risk of developing pressure ulcers. Assessing the skin every 4 hours (Choice A) may be too frequent or unnecessary unless there are specific concerns or orders. Limiting fluid intake (Choice B) is not directly related to skin assessment in an immobilized patient. Having special times for inspection to avoid interrupting routine care (Choice D) is not as crucial as using a standardized tool for consistent and comprehensive skin assessment.
Question 3 of 9
When caring for a client with diarrhea due to Shigella, which of the following precautions should the nurse take?
Correct Answer: A
Rationale: The correct precaution for Shigella infection is to wash hands thoroughly before and after contact with the client. Shigella is transmitted through the fecal-oral route, so hand hygiene is crucial in preventing its spread. Wearing a surgical mask or face shield is not necessary for Shigella as it is not primarily transmitted through respiratory droplets. While wearing a gown and gloves is important for standard precautions, the key precaution specific to Shigella is proper hand hygiene.
Question 4 of 9
A nurse at a health department is planning strategies related to heart disease. Which of the following activities should the nurse include as part of primary prevention?
Correct Answer: B
Rationale: Teaching about a healthy diet is considered a primary prevention activity. Primary prevention aims to prevent the onset of a disease or health problem. Educating individuals on healthy lifestyle choices, such as diet modification, falls under primary prevention. Providing cholesterol screening (choice A) is a secondary prevention measure aimed at early detection. Offering information about antihypertensive medications (choice C) falls under secondary prevention, focusing on controlling risk factors. Developing a list of cardiac rehabilitation programs (choice D) is part of tertiary prevention, focusing on rehabilitation and improving outcomes post-disease onset.
Question 5 of 9
Which nursing diagnosis would be a priority for a client admitted with a CVA (cerebral vascular accident)?
Correct Answer: A
Rationale: The correct answer is 'Risk for aspiration' as it is a priority concern in clients with a CVA due to potential swallowing difficulties. Aspiration poses immediate risks such as pneumonia, which can be life-threatening. Impaired physical mobility, while important, may not be as urgent as the risk for aspiration in this scenario. Disturbed sensory perception and interrupted family processes are not typically the most critical concerns in the acute phase of a CVA.
Question 6 of 9
A nurse in a provider's office is assessing a client who has heart failure. The client has gained weight since her last visit, and her ankles are edematous. Which of the following findings by the nurse is another clinical manifestation of fluid volume excess?
Correct Answer: A
Rationale: A bounding pulse is indicative of fluid volume excess. In this case, the client's weight gain and edematous ankles already suggest fluid volume overload. A bounding pulse occurs due to increased blood volume and pressure. Choices B, C, and D are not indicative of fluid volume excess. Decreased blood pressure, dry mucous membranes, and weak pulse are more commonly associated with conditions such as dehydration or hypovolemia, where there is a decrease in fluid volume rather than an excess.
Question 7 of 9
A client is receiving chemotherapy for breast cancer. Which laboratory value would be most important for the nurse to monitor?
Correct Answer: A
Rationale: The correct answer is to monitor the white blood cell count. Chemotherapy can lead to neutropenia, which is a decrease in white blood cells, particularly neutrophils. Neutropenia increases the risk of infections, making it crucial to monitor the white blood cell count during chemotherapy. Monitoring hemoglobin level is important but not as critical as white blood cell count in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer, making them less relevant to monitor in this situation.
Question 8 of 9
A healthcare provider is assessing a client's ability to balance. Which of the following actions is appropriate when the healthcare provider conducts a Romberg test?
Correct Answer: C
Rationale: The Romberg test is a neurological test that assesses proprioception and balance. To perform this test, the client is asked to stand with their feet together and arms at their sides while closing their eyes. By removing visual input, the test challenges the vestibular and proprioceptive systems. Choices A, B, and D are incorrect because they do not align with the proper procedure for conducting the Romberg test. Extending arms in front, walking heel to toe, or placing hands on hips are not part of the Romberg test protocol and may introduce variables that could affect the assessment of balance.
Question 9 of 9
A healthcare professional is assessing an adult client who has been immobile for the past 3 weeks. The healthcare professional should identify that which of the following findings requires further intervention?
Correct Answer: A
Rationale: Erythema on pressure points indicates potential skin breakdown due to prolonged immobility. It requires immediate intervention to prevent pressure ulcers. Lower-extremity pulse strength of 2+ is a normal finding, indicating adequate peripheral perfusion. Fluid intake of 3,000 mL per day is within the normal range and promotes hydration. A bowel movement every other day is a reasonable frequency for some individuals and does not necessarily indicate a need for immediate intervention in this scenario.
