When the healthcare provider is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should they measure?

Correct Answer: A

Rationale: When selecting the correct size of an oropharyngeal airway, the healthcare provider 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 maintain a clear air passage for exchange. Measuring from the corner of the eye to the top of the ear (Choice B) is inaccurate and not a standard measurement for selecting the size of an oropharyngeal airway. Measuring from the tip of the chin to the sternum (Choice C) is irrelevant to determining the correct size of the airway. Similarly, measuring from the tip of the nose to the earlobe (Choice D) is also incorrect and does not provide the necessary measurement for selecting an oropharyngeal airway size.

Correct Answer: D

Rationale: The correct answer is the capillary refill time of 3 seconds on the big toe. A capillary refill time longer than three seconds may indicate inadequate blood flow. Swollen feet, brown discoloration above the ankles, and leg pain are all signs of venous insufficiency to the lower extremities. These findings can suggest circulation issues and require further assessment and intervention. Therefore, they should be of more concern compared to the capillary refill time of 3 seconds on the big toe, which is within the normal range of 2-3 seconds.

Correct Answer: C

Rationale: When performing a paracentesis, the client must be sitting up to allow the fluid to settle in the lower abdomen. To prevent trauma to the bladder while inserting a needle to aspirate the fluid, the bladder must be empty. Choice A is incorrect as excessive fluid intake can make the procedure more difficult due to increased abdominal distension. Choice B is unrelated to the procedure of paracentesis. Choice D is incorrect as the client should be sitting up, not in the prone position, during the procedure.

Correct Answer: D

Rationale: The correct answer is 'urine.' Urine output is routinely measured to assess renal function and fluid balance. Choices A, B, and C are types of fluid output that are typically measured in a clinical setting. Chest tube drainage is monitored to evaluate drainage from the chest cavity, emesis refers to vomitus which can indicate gastrointestinal issues, and evaporative water from the respiratory tract is considered insensible loss and is not directly measured but estimated in overall fluid balance assessments.

Correct Answer: C

Rationale: The correct answer is 'The main therapeutic goals are comfort and better quality of life.' This statement reflects a proper understanding of palliative care, which focuses on improving the patient's quality of life and providing comfort. It does not necessarily mean a prognosis of less than 6 months or require hospitalization. Choice A is incorrect because palliative care can be provided regardless of the prognosis. Choice B is wrong as palliative care can be administered in various settings, not just hospitals. Choice D is inaccurate as palliative care aims to improve symptoms and quality of life, so medications may be adjusted but not necessarily stopped.

Correct Answer: A

Rationale: The correct instruction for a client undergoing mammography is not to use underarm deodorant. Underarm deodorant can cause confusing shadows on the X-ray film, affecting the accuracy of the mammogram. Choices B, C, and D are incorrect. While wearing comfortable clothing is advisable, it is not the primary instruction for mammography. Avoiding caffeine and bringing a list of current medications are not specific instructions related to mammography preparation and are therefore not the correct answers.

Correct Answer: D

Rationale: The correct answer is 'medication instruction.' This service involves educating the client on how to properly take their medications, which requires a certain level of expertise and skill. Grocery shopping, house cleaning, and transportation to physician's visits are considered unskilled services as they do not involve specialized knowledge or training. In contrast, medication instruction is a skilled service that necessitates specific training to ensure the client's safety and adherence to their medication regimen.

Correct Answer: D

Rationale: When removing hard contact lenses from an unresponsive client, the nurse should ensure that the lens is centered on the cornea before gently manipulating the lids to release the lens. This approach helps prevent scratching the cornea. Gently maneuvering the upper and lower eyelids assists in loosening the lens for easy removal. Options A, B, and C are incorrect because irrigating the eye, grasping the lens, or wearing sterile gloves are not recommended methods for removing hard contact lenses. It is crucial to handle the situation delicately to avoid causing harm or discomfort to the client.

Correct Answer: D

Rationale: Legal protection of confidentiality extends to both written and verbal information that is identifiable as individual private health information. Confidentiality in healthcare settings is vital to protect patients' privacy and trust. Choice A is incorrect because legal protection covers verbal information as well, not just written documentation. Choice B is incorrect as it mentions information not identifiable to a specific client, which wouldn't fall under legal protection of confidentiality. Choice C is incorrect as confidentiality extends beyond just the court system, impacting various healthcare settings and interactions. Therefore, the correct answer is D.
