1. When the nurse is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should she measure?
- A. corner of the mouth to the tragus of the ear
- B. corner of the eye to the top of the ear
- C. tip of the chin to the sternum
- D. tip of the nose to the earlobe
Correct answer: B
Rationale: Correct! When sizing an oropharyngeal airway, the nurse should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to reach the pharynx without being too long or too short. Choices B, C, and D are incorrect as they do not provide the correct anatomical landmarks for determining the size of an oropharyngeal airway. Measuring from the corner of the mouth to the tragus of the ear is a standard method to ensure proper airway size and prevent complications during airway management.
2. The client is unsure about making medical decisions as their disease progresses and wants to appoint someone to make these decisions. Which of the following options would be most appropriate?
- A. a living will
- B. informed consent
- C. a healthcare proxy
- D. non-informed consent
Correct answer: C
Rationale: The correct answer is 'a healthcare proxy.' A healthcare proxy involves the client appointing an individual to make medical decisions on their behalf if they become unable to do so. This option allows the client to choose someone they trust to act in their best interests. Choice A, 'a living will,' is a legal document that outlines a person's wishes regarding medical treatment in case they are unable to communicate their decisions. While it is important, it does not involve appointing someone to make decisions. Choice B, 'informed consent,' is a process where a healthcare provider explains a treatment or procedure, including its risks and benefits, to a patient who can then decide whether to proceed. This is not about appointing someone to make decisions on the patient's behalf. Choice D, 'non-informed consent,' is not a valid concept in healthcare. Informed consent is crucial for respecting a patient's autonomy and decision-making capacity.
3. What spinal change occurring with pregnancy alters mobility?
- A. Scoliosis.
- B. Kyphosis.
- C. Lordosis.
- D. Ankylosing spondylitis.
Correct answer: C
Rationale: The correct answer is 'Lordosis.' During pregnancy, the enlarging uterus places increased weight on the spine, causing an exaggerated inward curvature known as lordosis. This change alters mobility by shifting the center of gravity forward, leading to a compensatory change in posture. Scoliosis (choice A) is a sideways curvature of the spine, not typically associated with pregnancy. Kyphosis (choice B) is an exaggerated outward curvature of the spine, while ankylosing spondylitis (choice D) is a chronic inflammatory condition affecting the spine, neither of which are directly related to the spinal changes seen in pregnancy.
4. What is the 24-hour day-night cycle known as?
- A. circadian rhythm
- B. infradian rhythm
- C. ultradian rhythm
- D. non-REM rhythm
Correct answer: A
Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.
5. Under what circumstances can an individual receive medical care without giving informed consent?
- A. when the durable power of attorney for health care is not available
- B. in an emergency, life-or-death situation
- C. when the physician is not available for discussion with the client
- D. when they (clients) are not able to speak for themselves
Correct answer: B
Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.
