Correct Answer: D

Rationale: The correct action for the nurse to take when finding a radiation implant in the bed is to place the implant in a lead container using long-handled forceps. This action is crucial to minimize radiation exposure to both the patient and healthcare providers and ensure the safe disposal of the radioactive material. Calling the radiology department (choice A) may lead to unnecessary delays in addressing the immediate safety concern. Reinserting the implant into the vagina (choice B) is contraindicated and can cause harm. Applying double gloves to retrieve the implant for disposal (choice C) is not adequate for ensuring proper containment and handling of the radioactive implant, which requires specialized equipment like a lead container and long-handled forceps.

Correct Answer: C

Rationale: In the scenario described, the client presents with signs of fluid overload and hyponatremia. Restricting oral fluid intake is the appropriate intervention to manage fluid overload and correct hyponatremia. Increasing the intake of salty foods (Choice A) and administering NaCl supplements (Choice B) would exacerbate the sodium imbalance. Holding the client's loop diuretic (Choice D) is not directly related to addressing the fluid overload and hyponatremia.

Correct Answer: D

Rationale: Placing ID bands on the infant and mother is crucial to ensure correct identification and prevent mix-ups. This step is essential for maintaining proper identification of the newborn and the mother, facilitating safe care delivery. Before leaving the delivery room, ensuring proper identification is a priority to prevent any errors. Obtaining the infant's vital signs may be important but does not take precedence over ensuring correct identification. Observing the infant latching onto the breast is crucial for breastfeeding initiation but can be done after proper identification. Administering a vitamin K injection is also important but should not delay the immediate identification process.

Correct Answer: D

Rationale: When assessing a client with acute asthma, a cough and wheezing or musical breath sounds on expiration are typical findings. Pursed lip breathing and clubbing of fingers (choice A) are not common in acute asthma but could be seen in chronic respiratory conditions. Fever and high-pitched inspiratory stridor (choice B) are more indicative of croup or epiglottitis. A short expiratory phase and hemoptysis (choice C) are not typical findings in acute asthma.

Correct Answer: A

Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.
