Correct Answer: D

Rationale: Rationale: 1. Indispensable amino acids, also known as essential amino acids, must be obtained through the diet as the body cannot synthesize them. 2. Amino acids are the building blocks of proteins, so mentioning "indispensable amino acids" indicates understanding of essential dietary proteins. 3. Triglycerides are fats, not proteins, and not related to essential amino acids. 4. Dispensable amino acids can be synthesized by the body, so mentioning them would not indicate understanding of essential proteins.

Correct Answer: D

Rationale: The correct answer is D: Labyrinthitis. This condition presents with sudden onset vertigo, nausea, vomiting, tinnitus, and hearing loss, which are all symptoms described by the patient. Labyrinthitis is commonly caused by a viral infection affecting the inner ear, leading to inflammation of the labyrinth. This inflammation disrupts the balance and hearing functions of the inner ear, resulting in the symptoms mentioned. A: Ossiculitis involves inflammation of the middle ear bones, typically causing conductive hearing loss, not the sudden onset of vertigo and other symptoms described. B: Mnire's disease is characterized by recurrent episodes of vertigo, tinnitus, and hearing loss, but it typically does not present with sudden onset incapacitating vertigo. C: Ototoxicity is caused by exposure to certain medications or chemicals that damage the inner ear structures, leading to hearing loss. While hearing loss is a symptom, the sudden onset of vertigo is not typically associated with ototoxicity.

Correct Answer: D

Rationale: The correct answer is D: Hold the condom by the cuff upon withdrawal. This is important because holding the condom by the cuff helps prevent any potential spillage of bodily fluids. During withdrawal, holding the condom by the base prevents it from slipping off and minimizes the risk of exposure to sexually transmitted infections. Explanation of why other choices are incorrect: A: Attaching the condom prior to erection is incorrect as it may lead to breakage or slipping off during intercourse. B: Reusing a condom with the same partner is highly discouraged due to the risk of breakage, reduced effectiveness, and potential exposure to infections. C: Using skin lotion as a lubricant is not recommended as it can degrade the condom material, increasing the risk of breakage.

Correct Answer: A

Rationale: The correct answer is A: Charts legibly. This is accurate legally because clear and legible documentation is crucial for accurately conveying patient information, ensuring continuity of care, and meeting legal standards. Illegible handwriting can lead to errors in patient care and legal issues. Choice B is incorrect as labeling a patient as "belligerent" without evidence can be perceived as unprofessional and potentially harmful to the patient. Choice C is incorrect as writing an entry for another nurse can lead to inaccurate documentation and legal consequences. Choice D is incorrect because using correction fluid can raise suspicion of tampering with records and compromise the integrity of the documentation.

Correct Answer: A

Rationale: The correct answer is A: Breech presentation. Obesity can lead to a larger fetus, increasing the risk of breech presentation. The rationale is that excess fat can hinder the baby's ability to turn head down. Other choices are incorrect because: B: Ectopic pregnancy is not related to obesity, C: Birth defects can be influenced by maternal health but are not directly linked to obesity, and D: Venous thromboembolism is more associated with immobility and hypercoagulable states rather than obesity.
