Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?

Correct Answer: B

Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.

Correct Answer: A

Rationale: The correct answer is A, 'Monitoring a respiratory rate of 16 to 20 per minute'. When performing postural drainage and percussion, it is crucial to monitor the respiratory rate to ensure the safety and effectiveness of the procedure. Choice B, 'Assessing the client's ability to tolerate sitting and lying positions', while important, is not directly related to the specifics of postural drainage and percussion. Similarly, option C, 'Ensuring the client is free of signs of infection', although important, is not directly linked to the procedure. Option D, 'Knowing the time of the client's last food and fluid intake', might be relevant for other procedures, but it is not the primary consideration for postural drainage and percussion.

Correct Answer: D

Rationale: The correct answer is D. A medical record becomes a potential issue for a doctor or a nurse when it is inaccurate, incomplete, or inadequate. This is because a medical record is a key tool for healthcare professionals to track a patient's history, treatment, and progress. If the record is not accurate or complete, it can lead to misdiagnosis, incorrect treatment, or other potential problems in patient care. While missing records (Choice C) could be a problem, they do not directly implicate the doctor or nurse in the same way that inaccurate or inadequate records do. An extensive record (Choice A) or a record being subpoenaed in court (Choice B) are not inherently problematic for healthcare professionals and do not necessarily reflect negatively on their work.

Correct Answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

Correct Answer: D

Rationale: A written nursing care plan fundamentally serves to facilitate the development of a nursing diagnosis. This procedure involves analyzing patient data and identifying health problems that nurses can address independently. This analysis then aids in determining the most appropriate nursing interventions for the identified health issues. Although evaluating the achievement of nursing care goals is an important aspect, it is not the primary function of a nursing care plan. Similarly, while delivering quality nursing care is crucial, it is a broader concept that includes many other facets beyond just the initial nursing diagnosis and interventions.

Correct Answer: C

Rationale: The correct answer is C. While it is true that Mrs. Guevarra is delegating tasks to the nurse-aide, she does not necessarily have to directly supervise or evaluate the aide. She still retains the overall accountability for the care of the client, but direct supervision of the aide is not a requirement for delegation. Choice A is incorrect because the primary purpose of delegation is not instruction. Choice B is also incorrect because although Mrs. Guevarra is delegating tasks, she still retains accountability for those tasks. Finally, choice D is incorrect because the ability to perform the task being delegated is not a requirement for the delegator; the delegatee should have the necessary skills and knowledge to perform the delegated tasks.

Correct Answer: A

Rationale: The correct answer is 'Autonomy'. Autonomy refers to the patient's right to make their own decisions, which is being honored when a nurse signs a consent form. While beneficence (Choice D) is an important ethical principle that involves acting in the patient's best interest, it is not what is being primarily observed in this instance. Justice (Choice B) refers to fairness and equal treatment and is not specifically relevant to this scenario. Accountability (Choice C) pertains to being answerable for one's actions and decisions, but again, it is not the principle directly observed in this situation. Therefore, when a nurse signs a consent form, it is the principle of autonomy that is being observed.

Correct Answer: A

Rationale: Banana slices are the most suitable food option for toddlers to prevent choking. Toddlers are at a higher risk of choking due to their small airways and developing chewing abilities. Banana slices are soft, easy to chew, and less likely to cause choking compared to other options. Popcorn and hot dogs are common choking hazards for young children due to their shape and texture. While carrot sticks may be a healthy choice, they can also pose a choking risk due to their hardness and shape. Therefore, recommending banana slices to parents of toddlers is the safest choice to prevent choking incidents, making choice 'A' the correct answer. Choices 'B', 'C', and 'D' are incorrect because they can potentially cause choking in toddlers.

Correct Answer: A

Rationale: Following colostomy surgery, a healthy stoma should appear pink, moist, and slightly protruding from the abdomen, which is why option 'A' is the correct answer. A gray stoma (choice 'B') could indicate poor blood supply or necrosis, which is a serious complication. A dry stoma (choice 'C') is also not normal as it should be moist; a dry stoma may suggest dehydration or other complications. While a stoma can appear red (choice 'D'), this is not typically the normal color; it should usually be pink. Therefore, it's important for healthcare professionals to correctly identify the normal and abnormal appearances of a stoma to ensure proper patient care.
