Adult Health 2 Exam 1
1. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?
- A. Filtration
- B. Diffusion
- C. Osmosis
- D. Active transport
Correct answer: C
Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
2. During a bed bath, the nurse observes that a client's IV site is red and swollen. What should the nurse do first?
- A. Discontinue the IV under physician's guidance
- B. Apply a warm compress to the site
- C. Notify the physician
- D. Document the appearance of the site and continue the bath
Correct answer: C
Rationale: The correct first action when a nurse observes a red and swollen IV site during a bed bath is to notify the physician. This is crucial because prompt reporting allows for immediate intervention to prevent further complications. Discontinuing the IV (Choice A) should only be done under the physician's guidance to avoid any adverse effects and ensure proper care. Applying a warm compress (Choice B) may not address the underlying issue and could potentially worsen the situation if the cause is an infection or infiltration. Documenting the site's appearance and continuing the bath (Choice D) without immediate action might delay necessary treatment, leading to potential complications.
3. A client who is 24 weeks pregnant presents with a complaint of feeling dizzy when lying on her back. What is the best response by the nurse?
- A. Advise the client to lie on her side
- B. Encourage the client to drink more fluids
- C. Suggest the client elevate her legs when lying down
- D. Recommend the client take short walks throughout the day
Correct answer: A
Rationale: The correct answer is to advise the client to lie on her side. Lying on the side can prevent the compression of the vena cava, which can cause dizziness in pregnant women. Encouraging the client to drink more fluids (Choice B) may be beneficial for other conditions but is not the best response for dizziness when lying on her back. Suggesting the client elevate her legs when lying down (Choice C) is not directly related to the issue described by the client. Recommending the client take short walks throughout the day (Choice D) may be helpful for other pregnancy-related symptoms but is not the most appropriate action for dizziness when lying on her back.
4. A client with a severe peanut allergy accidentally ingested peanut-containing food and is experiencing anaphylaxis. What is the nurse's priority action?
- A. Administer an epinephrine injection
- B. Call for immediate medical help
- C. Monitor airway, breathing, and circulation
- D. All of the above
Correct answer: A
Rationale: The priority action for a client experiencing anaphylaxis due to a severe peanut allergy is to administer an epinephrine injection. Epinephrine is the first-line treatment for anaphylaxis as it can rapidly reverse the severe allergic reaction. While calling for immediate medical help is important, administering epinephrine takes precedence because it can be life-saving in this situation. Monitoring airway, breathing, and circulation is essential in managing anaphylaxis, but administering epinephrine is the priority action to halt the progression of the allergic reaction and stabilize the client's condition. Therefore, 'Administer an epinephrine injection' is the most critical initial intervention.
5. When providing care for a client receiving palliative care for terminal cancer, what should the nurse prioritize?
- A. Pain management
- B. Arranging family visits
- C. Discussing advance directives
- D. Providing nutritional support
Correct answer: A
Rationale: When caring for a client receiving palliative care for terminal cancer, the nurse should prioritize pain management. Effective pain management is crucial in enhancing the quality of life for terminally ill patients. While arranging family visits and discussing advance directives are important aspects of care, pain management takes precedence in providing comfort and alleviating suffering. Nutritional support is essential but may be of lesser priority compared to pain management in this context.
