Fundamentals of Nursing HESI

Correct Answer: A

Rationale: The correct answer is A. Obtaining cotton balls for tracheostomy care is not recommended due to the risk of fiber contamination. Sterile gauze should be used instead. Choice B, using a sterile water bottle, is a correct and appropriate action for tracheostomy care to maintain cleanliness. Choice C, checking the suction equipment, is also a necessary step to ensure it is functioning properly for the procedure. Choice D, wearing a sterile gown, is a standard precaution to maintain a sterile environment during tracheostomy care.

Correct Answer: A

Rationale: The correct answer is A: Washing dishes. Washing dishes is a lower-intensity activity that is suitable for a client recovering from lung cancer. This activity does not require significant physical exertion and allows the client to engage in a manageable task while still following the provider's instructions for lower-intensity activities. Choices B, C, and D involve more physical effort and may not be appropriate for a client recovering from lung cancer, as they require more energy and physical strain, which could hinder the recovery process.

Correct Answer: B

Rationale: The correct answer is B. A Glasgow Coma Scale of 8 with regular respirations accurately describes a non-responsive state with independent breathing. Choice A is incorrect because 'comatose' implies a deeper state of unconsciousness than what is described in the scenario. Choice C is inaccurate as the client is not merely sleeping but non-responsive. Choice D is incorrect as a Glasgow Coma Scale of 13 indicates a higher level of consciousness than what is presented in the scenario.

Correct Answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

Correct Answer: C

Rationale: When preparing to insert an IV catheter, stroking the extremity before insertion helps to visualize veins, making it easier to locate a suitable vein for catheter insertion. Choosing the most distal site on the extremity is correct because veins more distal are preferred for IV catheter insertion. Applying a cool compress to the extremity before insertion is unnecessary and not a standard practice. Placing the tourniquet below the proposed insertion site is incorrect; the tourniquet should be placed above the proposed insertion site to help engorge the veins for easier visualization and access.
