Correct Answer: C

Rationale: Disturbed Body Image is the most appropriate nursing diagnosis for a client with a new colostomy. A new colostomy can significantly impact a person's body image and self-esteem due to the physical changes it brings. This can lead to emotional distress, adjustment issues, and concerns about body image. Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are not directly related to the psychosocial impact of a new colostomy and are therefore not as relevant in this context. While Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are important nursing diagnoses, they are not the priority when considering the psychological and emotional effects of a new colostomy.

Correct Answer: B

Rationale: In the scenario described, where multiple passengers on an airliner experience sudden weakness and breathing difficulty simultaneously, the most likely cause is chemical exposure. This is because a sudden onset of similar symptoms in a group of individuals suggests a common environmental factor affecting them. Options A, C, and D are less likely as they do not explain a sudden onset of symptoms in multiple individuals simultaneously. Asian flu (Option A) is a viral infection and would not typically result in sudden symptoms in multiple individuals at the same time. Bacterial pneumonia (Option C) is a localized infection and not a probable cause for a sudden onset of symptoms in a group. An allergic reaction (Option D) would usually occur in individuals with specific allergies rather than affecting a group of passengers at the same time.

Correct Answer: B

Rationale: The correct answer is B: Eclampsia. Eclampsia is a disorder of pregnancy characterized by hypertension, proteinuria, and edema. This condition can cause seizures and/or coma but does not typically present with vaginal bleeding. Choices A, C, and D are abnormal conditions that can cause bleeding, particularly in the third trimester. Placenta previa (choice A) is a condition where the placenta partially or completely covers the cervix, leading to vaginal bleeding. Abruptio placentae (choice C) is the premature separation of the placenta from the uterine wall, causing vaginal bleeding. Uterine rupture (choice D) is a serious obstetrical emergency where the uterus tears during pregnancy or childbirth, resulting in severe bleeding.

Correct Answer: D

Rationale: The correct answer is Morton's neuroma. Morton's neuroma is a small mass or tumor in a digital nerve of the foot, causing symptoms such as pain and difficulty walking. Hallux valgus is commonly known as a bunion and involves the deviation of the big toe towards the other toes. Hammertoe is a condition where one or more toes are bent in a claw-like position. Plantar fasciitis is characterized by pain and inflammation in the arch of the foot, not typically associated with a mass causing difficulty walking.

Correct Answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.
