HESI Practice Test for Fundamentals

Correct Answer: D

Rationale: The correct answer is 'Discipline.' In this scenario, discipline is exemplified by following a structured and comprehensive assessment process, as seen in the head-to-toe approach. Confidence (choice A) relates to self-assurance and belief in one's abilities, which is not the primary critical thinking demonstrated in this situation. Perseverance (choice B) is the persistence in achieving goals despite challenges, not directly related to the systematic assessment process. Integrity (choice C) pertains to honesty and ethical behavior, which are important traits but not the critical thinking skill exemplified by the structured assessment process shown in the head-to-toe approach.

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.

Correct Answer: B

Rationale: Maintaining sterile technique when performing tracheostomy care is essential in preventing infections and complications. Option A is incorrect because povidone-iodine may be too harsh for cleaning around the stoma and can lead to skin irritation. Option C is incorrect because suctioning a tracheostomy should be done using sterile technique to minimize the risk of introducing pathogens. Option D is incorrect as tracheostomy ties need to be changed more frequently, usually every 1-2 days, to prevent skin breakdown and infection.

Correct Answer: A

Rationale: The initial priority when admitting a client suspected of having pulmonary tuberculosis is to implement airborne precautions to prevent the spread of the disease. Airborne precautions include wearing a mask and placing the client in a negative pressure room. Obtaining a sputum culture is essential for confirming the diagnosis, but ensuring infection control measures come first to protect others. Administering antituberculosis medications is important but should be initiated after implementing necessary precautions. Recommending a screening test for close contacts is relevant but is a secondary concern compared to immediate infection control measures.

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.
