Fundamentals of Nursing HESI

Correct Answer: C

Rationale: The correct dosage calculation is to divide the prescribed dose by the concentration of the medication to determine the volume needed. In this case, 3 mg (prescribed dose) divided by 4 mg/mL (concentration) equals 0.75 mL. Therefore, the healthcare provider should administer 0.75 mL of hydromorphone to the client. Choices A, B, and D are incorrect because they do not accurately calculate the required volume based on the prescription and concentration provided.

Correct Answer: D

Rationale: The correct answer is D: 'I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or other medications that increase the risk of bleeding. Choices A, B, and C are correct statements that show understanding of warfarin therapy, such as the importance of avoiding foods high in vitamin K, taking medication consistently, and using a soft toothbrush to prevent gum bleeding.

Correct Answer: A

Rationale: The correct answer is to make sure two fingers can fit under the sleeve. This allows for proper circulation and ensures that the sleeve is not too tight, which can lead to complications such as impaired blood flow or tissue damage. Choice B is incorrect because applying the sleeve tightly can actually cause harm rather than prevent blood clots. Choice C is incorrect as snugness alone may not guarantee proper fit. Choice D is incorrect as a sleeve that is too loose can be ineffective in providing the necessary compression.

Correct Answer: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

Correct Answer: C

Rationale: The correct answer is C. Telangiectatic nevi, often referred to as 'stork bites,' are common birthmarks in infants and are considered normal. These birthmarks usually fade and disappear as the child grows older. Choices A, B, and D are incorrect because Mongolian spots are bluish-gray birthmarks commonly found in darker-skinned infants, port wine stains are vascular birthmarks that typically do not disappear, and surgical removal is not recommended for telangiectatic nevi as they usually resolve on their own.
