1. When working with a couple at risk of bearing a child with a genetic abnormality, what is most important for the nurse to incorporate into the plan of care?
- A. Gathering information from at least three generations
- B. Informing the couple of the need for a wide range of information
- C. Maintaining the confidentiality of the information
- D. Presenting the information in a nondirective manner
Correct answer: D
Rationale: When counseling a couple at risk of genetic abnormalities, it is crucial to present information in a nondirective manner. This approach allows the couple to make informed decisions without feeling pressured or influenced. Gathering information from at least three generations (Choice A) may be relevant for genetic counseling but is not the most critical aspect in this scenario. Informing the couple of the need for a wide range of information (Choice B) is too general and does not address the specific approach needed in this situation. Maintaining the confidentiality of the information (Choice C) is important but not the top priority compared to presenting information in a nondirective manner.
2. What is a causative factor of Hirschsprung disease?
- A. Frequent evacuation of solids, liquid, and gases
- B. Excessive peristaltic movement
- C. The absence of parasympathetic ganglion cells in a portion of the colon
- D. One portion of the bowel telescoping into another
Correct answer: C
Rationale: The correct answer is C: The absence of parasympathetic ganglion cells in a portion of the colon is a causative factor of Hirschsprung disease. This absence leads to the inability of the affected segment of the colon to relax, causing a functional obstruction. Choices A, B, and D are incorrect. Frequent evacuation of solids, liquid, and gases, excessive peristaltic movement, and one portion of the bowel telescoping into another are not causative factors of Hirschsprung disease.
3. Epidemiology is directly concerned with which of the following?
- A. factors influencing occurrence and distribution of diseases, defects, disability, or death of groups of individuals
- B. vital health statistics
- C. environmental sanitation
- D. treatment of a communicable disease
Correct answer: A
Rationale: Corrected Rationale: Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. It focuses on identifying and understanding the factors that influence the occurrence and distribution of diseases, defects, disability, or death of groups of individuals. Therefore, the correct answer is A. Choice B, vital health statistics, is not the primary focus of epidemiology. While vital health statistics may be used in epidemiological studies, it is not the direct concern of epidemiology. Choice C, environmental sanitation, although important for public health, is not the main focus of epidemiology. Epidemiology is more concerned with the factors influencing disease occurrence and distribution, rather than environmental sanitation. Choice D, treatment of a communicable disease, is more related to clinical medicine rather than epidemiology. Epidemiology is more focused on prevention, control, and understanding the patterns and causes of diseases rather than their treatment.
4. What is the primary role of the sinoatrial (SA) node in the heart?
- A. Pacemaker of the heart
- B. Blood pressure regulation
- C. Electrical conduction delay
- D. Stimulating muscle contraction
Correct answer: A
Rationale: The correct answer is A: Pacemaker of the heart. The SA node, known as the natural pacemaker, initiates the electrical impulses that set the rhythm for the heartbeat. It is responsible for coordinating the heart's contractions by generating electrical signals at regular intervals. Choice B is incorrect as the SA node's primary function is not related to blood pressure regulation. Choice C is incorrect as the SA node does not cause electrical conduction delay but rather initiates and conducts the electrical impulses. Choice D is incorrect as the SA node does not directly stimulate muscle contraction but rather initiates the electrical events that lead to muscle contraction.
5. During the initial physical assessment of a newly admitted client with a pressure ulcer, an LPN observes that the client's skin is dry and scaly. The nurse applies emollients and reinforces the dressing on the pressure ulcer. Legally, were the nurse's actions adequate?
- A. The nurse should have also initiated a plan to increase activity.
- B. The nurse provided supportive nursing care for the well-being of the client.
- C. Debridement of the pressure ulcer should have been performed before applying the dressing.
- D. Treatment should not have been initiated until the healthcare provider's prescriptions were received.
Correct answer: B
Rationale: The correct answer is B. Providing supportive nursing care, such as applying emollients and reinforcing the dressing on the pressure ulcer, meets the immediate needs of the client and is in line with legal and professional standards. Option A is incorrect because increasing activity may not be directly related to the immediate skin care needs of the client. Option C is incorrect as debridement might not be immediately necessary based on the initial assessment. Option D is incorrect as nurses are often authorized to initiate treatments within their scope of practice without waiting for healthcare provider prescriptions, especially for routine care like skin moisturization and dressing reinforcement.
