Correct Answer: B

Rationale: The correct answer is A: Eggs. Eggs are considered a complete protein because they contain all 9 essential amino acids required by the human body. This makes them a high-quality protein source. Corn (B), peanuts (C), and sunflower seeds (D) are not complete proteins as they lack one or more of the essential amino acids. Corn is deficient in lysine, peanuts are deficient in methionine, and sunflower seeds are deficient in lysine. Therefore, only eggs provide all the essential amino acids necessary for optimal health and proper bodily functions.

Correct Answer: D

Rationale: The correct answer is D because the patient demonstrates orientation to person (knows their name), place (knows they are at the hospital in Victoria), and time (knows it is February of a new year – 2009). This indicates intact orientation across all three domains. Choice A is incorrect as the patient is unsure of their location and the year. Choice B is incorrect as the patient is confused about the date. Choice C is incorrect as the patient is uncertain about the date and only guesses their location.

Correct Answer: A

Rationale: The correct answer is A because asking "Why haven't you taken your insulin?" may put the patient on the defensive. This question can come across as accusatory or judgmental, potentially making the patient feel guilty or defensive. It may hinder open communication and lead to a breakdown in the nurse-patient relationship. Explanation of other choices: B: While the question may be an attempt to gather information, it lacks sensitivity and may not promote open dialogue. C: Involving the patient's wife without the patient's consent may breach confidentiality and undermine the patient's autonomy. D: While asking the question may reveal reasons for the behavior, it is not the best approach as it can create a barrier to effective communication.

Correct Answer: C

Rationale: The correct answer is C: pernicious anemia. Pernicious anemia is caused by vitamin B12 deficiency, leading to impaired red blood cell production but does not directly affect clotting factors. Metastatic liver cancer (A) can cause liver dysfunction and decreased production of clotting factors, increasing bleeding risk. Gram-negative septicemia (B) can lead to disseminated intravascular coagulation and excessive bleeding. Iron-deficiency anemia (D) can result in microcytic red blood cells and decreased oxygen delivery but does not directly increase bleeding potential.

Correct Answer: D

Rationale: The correct answer is D: Huntington's chorea. Huntington's chorea is a genetic disorder characterized by involuntary, writhing, and twisting movements of the face and limbs, known as chorea. This is due to degeneration of certain brain cells. Epilepsy (A) involves seizures, not specific movements. Parkinson's (B) is characterized by tremors and rigidity, not chorea. Multiple sclerosis (C) affects the central nervous system, causing a variety of symptoms, but not typically chorea.
