HESI Practice Test for Fundamentals

Correct Answer: B

Rationale: The correct instruction for using a metered-dose inhaler is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to be absorbed more effectively in the lungs. Inhaling quickly and deeply while pressing down on the inhaler (Choice A) may cause the medication to deposit in the mouth and throat rather than reaching the lungs. Exhaling immediately after inhaling the medication (Choice C) may also lead to medication wastage. Shaking the inhaler before each use (Choice D) is not necessary for all types of inhalers and can sometimes cause improper drug delivery.

Correct Answer: B

Rationale: Restlessness and increased mucus production are common signs of gastrointestinal issues or reflux in infants, which could explain the symptoms of spitting up and excessive gas. Increased temperature and lethargy (Choice A) are more indicative of an infection rather than gastrointestinal issues. Increased sleeping and listlessness (Choice C) are not typical signs associated with the symptoms described. Diarrhea and poor skin turgor (Choice D) are not directly related to the symptoms of spitting up and gas in this scenario.

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.

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: C

Rationale: The correct answer is C. Skipping meals to lose weight may indicate an eating disorder or significant distress, which can have serious health implications. This behavior raises concerns about the adolescent's physical and mental well-being. The nurse should prioritize addressing potential eating disorders and body image issues in this situation. Choices A, B, and D, while important, do not pose an immediate risk to the adolescent's health or well-being compared to the potential consequences of disordered eating behavior.
