Which of the ff. statements does the nurse understand is true concerning air conduction of sound in the ear?
- A. It is caused by the vibration of bones in the skull.
- B. It is less efficient than bone conduction.
- C. It is heard longer than bone conduction.
- D. It is caused by transmission of heat through the air.
Correct Answer: B
Rationale: The correct answer is B because air conduction is less efficient than bone conduction due to the sound waves traveling through the air in the ear canal, which can be hindered by factors like blockages or obstructions. This results in a weaker and less clear sound transmission compared to bone conduction, where sound waves are transmitted directly through the bones of the skull, bypassing any potential obstructions in the ear canal.
Incorrect choices:
A: This statement is incorrect as air conduction of sound in the ear is not caused by the vibration of bones in the skull.
C: This statement is incorrect as air conduction is typically heard for a shorter duration than bone conduction.
D: This statement is incorrect as air conduction of sound in the ear is not caused by the transmission of heat through the air, but rather by sound waves traveling through the ear canal.

A client has been diagnosed with renal failure and is admitted for dialysis. Which of the ff is the nurse’s responsibility as the client undergone dialysis?
- A. Keeping dialysis supplies in a clean area
- B. Inspecting the catheter insertion site for signs of infection
- C. Weighing the client before and after the procedure
- D. washing hands before and after handling the catheter
Correct Answer: C
Rationale: The correct answer is C: Weighing the client before and after the procedure. This is crucial as it helps monitor fluid removal during dialysis, ensuring the process is effective and safe. Weighing helps determine if the correct amount of fluid has been removed.
A: Keeping dialysis supplies in a clean area is important for infection control but not a direct responsibility during the procedure.
B: Inspecting the catheter insertion site for signs of infection is essential for monitoring the site's health but not a direct responsibility during dialysis.
D: Washing hands before and after handling the catheter is a general infection control measure but not specific to the dialysis procedure itself.
The nurse begins a shift assessment by examining a surgical dressing that is saturated with serosanguineous drainage on a patient who had open abdominal surgery yesterday (or 1 day ago). Which type of assessment approach is the nurse using?
- A. Gordon’s Functional Health Patterns
- B. Activity-exercise pattern assessment
- C. General to specific assessment
- D. Problem-oriented assessment
Correct Answer: C
Rationale: The correct answer is C: General to specific assessment. In this scenario, the nurse is starting with a broad assessment of the surgical dressing and the type of drainage present, then will progress to more specific assessments based on the findings. This approach allows for a systematic and comprehensive evaluation of the patient's condition by moving from general observations to detailed examinations.
Explanation:
1. General assessment: The nurse is initially assessing the overall appearance of the surgical dressing and the type of drainage.
2. Specific assessment: Based on the initial findings, the nurse will proceed to conduct more focused assessments, such as checking for signs of infection, monitoring vital signs, and assessing the surgical site for any complications.
Other choices are incorrect:
A: Gordon’s Functional Health Patterns - This framework focuses on assessing different aspects of an individual's health patterns, such as activity level, sleep patterns, and coping mechanisms. It is not the most appropriate approach in this situation.
B: Activity-exercise pattern assessment - This type of assessment focuses
Which action by the nurse is appropriate?
- A. Observe the patient for abnormal bleeding.
- B. Notify the physician and expect an order to increase the warfarin dose.
- C. Advise the patient to double today’s dose of warfarin.
- D. Administer Vit. K per protocol.
Correct Answer: A
Rationale: The correct answer is A because observing the patient for abnormal bleeding is an appropriate action to monitor for potential complications of warfarin therapy. This aligns with the nursing role in assessing and monitoring patient responses to treatment.
B is incorrect as increasing warfarin dose without physician order can lead to adverse effects. C is incorrect as altering the dose without medical advice can be dangerous. D is incorrect as administering Vitamin K would counteract the effects of warfarin, which is used to prevent blood clotting.
60 year-old Mrs. Torres arrived just in time for her doctor’s appointment. She complains of pain and stiffness in her back. She is suspected of having osteoporosis. Nurse Ariane will inform Mrs. Torres that the primary complication of osteoporosis is:
- A. Increased trabeculae
- B. poor posture
- C. chronic pain
- D. fractures
Correct Answer: D
Rationale: The correct answer is D: fractures. Osteoporosis weakens bones, making them more prone to fractures. Fractures are the primary complication of osteoporosis due to decreased bone density. Increased trabeculae (A) is incorrect as osteoporosis leads to decreased bone density, not increased. Poor posture (B) may be a result of osteoporosis but is not its primary complication. Chronic pain (C) can occur with osteoporosis but is not as directly linked as fractures.
Before a cancer receiving total parenteral nutrition (TPN) resumes a normal diet, the nurse teaches him about dietary sources of minerals. Which foods are good sources of zinc?
- A. Fruits and yellow vegetables
- B. Fruits and green vegetables
- C. Yeast and legumes
- D. Whole grains and meats
Correct Answer: D
Rationale: The correct answer is D: Whole grains and meats. Zinc is mainly found in animal-based foods like meats and seafood. Meats, particularly red meats, are rich sources of zinc. Whole grains like wheat, rice, and oats also contain zinc. Legumes (Choice C) are sources of other minerals but not high in zinc. Fruits and vegetables (Choices A and B) are not significant sources of zinc. The correct answer provides the best options for the cancer patient to obtain an adequate amount of zinc for recovery.
