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. A healthcare provider is assessing a child with suspected Kawasaki disease. What clinical manifestation is the healthcare provider likely to observe?
- A. Generalized rash
- B. Peeling skin on the hands and feet
- C. High fever
- D. Low-grade fever
Correct answer: B
Rationale: Peeling skin on the hands and feet is a characteristic clinical manifestation of Kawasaki disease, known as desquamation. This occurs during the convalescent phase of the illness. While Kawasaki disease is associated with a high fever, which is a common early sign, and can also present with other symptoms like conjunctivitis, mucous membrane changes, and lymphadenopathy, the peeling skin on the hands and feet is a classic feature that distinguishes Kawasaki disease from other conditions. Generalized rash is not a specific hallmark of Kawasaki disease, and low-grade fever is not typically associated with this condition. Therefore, the correct answer is B, peeling skin on the hands and feet, which is a key feature of Kawasaki disease.
3. A female client with obsessive-compulsive disorder (OCD) is describing her obsessions and compulsions and asks the nurse why these make her feel safer. What information should the nurse include in this client's teaching plan? (select one that does not apply.)
- A. Compulsions relieve anxiety
- B. Anxiety is the key reason for OCD
- C. Obsessions cause compulsions
- D. Obsessive thoughts are linked to levels of neurochemicals
Correct answer: C
Rationale: The correct answer is C. Obsessions do not cause compulsions; rather, obsessions are intrusive, unwanted thoughts, images, or urges that trigger intensely distressing feelings, while compulsions are repetitive behaviors or mental acts that a person feels driven to perform in response to an obsession or according to rules that must be applied rigidly. Choices A, B, and D are incorrect. Choice A is incorrect because compulsions are behaviors or mental acts aimed at reducing distress or preventing a dreaded event or situation. Choice B is incorrect because while anxiety is often a significant component of OCD, it is not the only reason for the disorder. Choice D is incorrect because obsessive thoughts are not solely linked to levels of neurochemicals but are more complex and multifactorial.
4. The nurse observes an UAP positioning a newly admitted client who has a seizure disorder. The client is supine, and the UAP is placing soft pillows along the side rails. Which action should the nurse implement?
- A. Instruct the UAP to obtain soft blankets to secure to the side rails instead of pillows
- B. Ensure that the UAP has placed pillows effectively to protect the client
- C. Ask the UAP to use some pillows to prop the client in a side-lying position
- D. Assume responsibility for placing the pillows while the UAP completes another task
Correct answer: A
Rationale: Using soft blankets to secure to the side rails provides better protection during a seizure as they are more secure and less likely to shift compared to pillows. This action helps prevent injury to the client by minimizing the risk of falling or hitting the side rails during a seizure. Choices B and C do not address the issue of using more secure materials. Choice D is inappropriate as it is important for the nurse to ensure the safety and well-being of the client by using the most appropriate protective measures.
5. Why is it important to initiate nursing interventions that promote good nutrition, rest, exercise, and stress reduction for clients diagnosed with an HIV infection?
- A. Prevent the spread of infection to others
- B. Improve the function of the immune system
- C. Increase the ability to carry out activities of daily living
- D. Promote a feeling of general well-being
Correct answer: B
Rationale: The correct answer is B: 'Improve the function of the immune system.' Initiating interventions focusing on good nutrition, rest, exercise, and stress reduction aims to enhance the immune system function in clients with HIV infection. For individuals with HIV, maintaining a strong immune system is crucial in fighting the virus and preventing opportunistic infections. Choices A, C, and D are important aspects of care but are secondary to the primary goal of boosting the immune system to combat the effects of the HIV virus.
