HESI Fundamentals Exam

Correct Answer: A

Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.

Correct Answer: B

Rationale: When assessing body alignment for an immobilized patient, the nurse should use the lateral position. This position helps in assessing alignment and preventing complications such as pressure ulcers. The supine position (Choice A) may not provide an accurate assessment of body alignment in an immobilized patient. While a lateral position with positioning supports (Choice C) may be used for comfort, it is not specifically for assessing body alignment. Using the supine position without a pillow under the patient's head (Choice D) is not ideal for assessing body alignment in an immobilized patient as it may not accurately reflect the patient's overall alignment.

Correct Answer: A

Rationale: Administering a bronchodilator as prescribed is the most appropriate initial action for managing asthma-related shortness of breath. Bronchodilators help to open up the airways quickly, providing relief for the client. Encouraging deep breathing exercises may be beneficial in some situations but should not be the first action for acute shortness of breath in asthma. Positioning the client in high Fowler's position can also help improve breathing, but administering the bronchodilator takes precedence. Obtaining a peak flow reading is important in asthma management, but it is not the initial action needed to address acute shortness of breath.

Correct Answer: A

Rationale: The pulse deficit is calculated by finding the difference between the apical and radial pulse rates. In this case, the difference is 84 - 68 = 16. This indicates that there is a pulse deficit of 16 beats per minute. Choices B, C, and D are incorrect as they do not accurately reflect the difference between the two pulse rates.

Correct Answer: A

Rationale: The ventrogluteal site is considered the safest for intramuscular injections in young adult clients due to its location away from major nerves and blood vessels. The ventrogluteal site is preferred over the dorsogluteal site, as the latter is associated with a higher risk of injury to the sciatic nerve. The deltoid site is commonly used for vaccines but may not be suitable for all intramuscular injections due to smaller muscle mass. The vastus lateralis site is often used in infants and young children, but in young adults, the ventrogluteal site is preferred for safety and efficacy.
