Which of the following structures is responsible for storing and concentrating bile produced by the liver until it is needed for digestion?

Correct Answer: B

Rationale: The gallbladder is the structure responsible for storing and concentrating bile produced by the liver until it is needed for digestion. Bile is a digestive fluid that helps in the breakdown of fats during the digestive process. When food containing fats enters the small intestine, the gallbladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, storing it until it is needed for digestion.

Correct Answer: C

Rationale: Ménière's disease is characterized by the triad of symptoms including progressive sensorineural hearing loss, tinnitus, and vertigo. The audiometric testing in Ménière's disease often shows a "carrot-shaped" configuration, which refers to low-frequency hearing loss initially and eventually spreading to involve higher frequencies. This distinctive pattern of hearing loss helps differentiate Ménière's disease from other causes like Presbycusis (age-related hearing loss) or Noise-induced hearing loss. Acoustic neuroma can present with unilateral sensorineural hearing loss but typically does not exhibit the specific "carrot-shaped" configuration seen in Ménière's disease.

Correct Answer: C

Rationale: In a critically ill patient admitted to the ICU with acute renal failure requiring renal replacement therapy (RRT), the healthcare team should prioritize the initiation of continuous renal replacement therapy (CRRT). CRRT is preferred in critically ill patients with hemodynamic instability as it allows for slow and continuous removal of solutes and fluids, making it a safer option compared to intermittent hemodialysis. CRRT can also provide better control of volume status and electrolyte imbalances over a longer period, which is beneficial in critically ill patients who are hemodynamically unstable. Peritoneal dialysis is not commonly used in the ICU setting for acute renal failure requiring RRT, and loop diuretics are not effective in treating acute renal failure. Temporary hemodialysis catheters may also be used, but CRRT is generally preferred in critically ill patients for better hemodynamic tolerance and control of solute and fluid removal.

Correct Answer: C

Rationale: It is crucial to have a complete set of surgical instruments for any surgical procedure to ensure patient safety and the success of the surgery. If the nurse notices that the surgical instrument tray is incomplete, the best course of action is to inform the sterile processing department immediately. By doing so, the missing instruments can be promptly provided, ensuring that the surgical team has all the necessary tools for the procedure. Proceeding with the procedure using incomplete instruments can compromise patient safety and the quality of care provided. Documenting the missing instruments in the surgical count log is important for record-keeping purposes but should not delay the immediate action of requesting additional instruments. Borrowing instruments from another OR is not recommended as it can create confusion, potential cross-contamination, and disrupt the workflow of another surgical team.

Correct Answer: B

Rationale: The type of pregnancy test is not a factor that should be considered by the nurse or the pregnant woman in interpreting the results of a pregnancy test. Factors such as the last menstrual period, previous pregnancy history, and menstrual cycle length play a crucial role in determining the reliability and accuracy of the pregnancy test results.

Correct Answer: D

Rationale: Patients prescribed proton pump inhibitors (PPIs) for the treatment of GERD should be closely monitored for the development of osteoporosis. PPIs have been associated with an increased risk of developing osteoporotic fractures, particularly in long-term users. This risk is thought to be due to decreased calcium absorption as stomach acidity is reduced by PPIs, leading to potential alterations in bone metabolism and density. Therefore, it is important for healthcare providers to assess bone health, educate patients on calcium and vitamin D supplementation, and consider other risk factors for osteoporosis in individuals taking PPIs long-term. While hypoglycemia, hyperkalemia, and Clostridium difficile infection may be seen as adverse effects with other medications or conditions, osteoporosis is the adverse effect most closely monitored in patients taking PPIs for GERD.

Correct Answer: B

Rationale: Helping the family recognize the problem is the most appropriate intervention to assist them in performing health tasks. By recognizing the problem, the family can better understand the need for action and be motivated to take steps to address it. This intervention enables the family to become more engaged in their healthcare decision-making process and enhances their ability to effectively manage their health tasks. It empowers them to seek appropriate health resources and make informed choices in promoting their health and well-being. Ultimately, by acknowledging the problem, the family is better equipped to initiate positive changes and improve their overall health outcomes.

Correct Answer: C

Rationale: Qualitative research design focuses on gaining an in-depth understanding of attitudes, beliefs, motivations, and behaviors of individuals or groups. It does not typically involve statistical analysis or estimation of relationships between variables like quantitative designs do. Qualitative research involves collecting data through methods such as interviews, observations, or focus groups to provide rich and detailed insights into the experiences and perspectives of the participants. The emphasis is on understanding the meanings individuals attach to their experiences, rather than generalizing findings to a larger population.

Correct Answer: A

Rationale: The presentation described in the question is classic for anterior uveitis. Anterior uveitis is an inflammatory condition affecting the iris and ciliary body and is characterized by redness, pain, and photophobia. Slit-lamp examination typically reveals ciliary injection (redness around the iris), corneal edema, and a mid-dilated pupil with a fixed reaction to light due to inflammation causing spasm of the iris muscles. Acute angle-closure glaucoma would present with similar symptoms but would also have increased intraocular pressure, which is not mentioned in the presentation. Endophthalmitis is an infection of the intraocular cavities and would typically present with more severe symptoms, such as severe pain, vision loss, and presence of pus in the eye. Corneal abrasion would present with pain, foreign body sensation, and possibly tearing but would not cause ciliary injection or fixed pupil reaction as
