HESI LPN
Adult Health 2 Exam 1 Questions
Question 1 of 5
Prior to administering morphine sulfate (Morphine), the nurse takes the client's vital signs. Based on which finding should the nurse withhold administration of the medication until the charge nurse is notified?
Correct Answer: C
Rationale: The correct answer is C because a low respiratory rate is a critical concern when administering opioids like morphine, as they can suppress breathing. A high pulse rate (choice B) and high blood pressure (choice D) are not immediate contraindications for administering morphine. A slightly elevated temperature (choice A) may not necessarily require withholding morphine.
Question 2 of 5
What is the most important information for the nurse to provide to a client with a diagnosis of major depressive disorder who is started on a selective serotonin reuptake inhibitor (SSRI)?
Correct Answer: C
Rationale: The correct answer is C: 'Report any thoughts of self-harm immediately.' When starting an SSRI, clients should be informed to report any thoughts of self-harm promptly. SSRIs can initially increase suicidal ideation, especially in the early stages of treatment. This information is crucial for the client's safety and well-being. Choices A, B, and D are incorrect because taking the medication with food, avoiding foods high in tyramine, and expecting immediate improvement within 24 hours are not the most critical pieces of information for a client starting on an SSRI.
Question 3 of 5
Which structures are located in the subcutaneous layer of the skin?
Correct Answer: D
Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.
Question 4 of 5
What is the primary function of neutrophils?
Correct Answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
Question 5 of 5
A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?
Correct Answer: B
Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
