Mickey, a 6-year-old child with a congenital heart disorder is admitted with congestive heart failure. Digoxin (lanoxin) 0.12 mg is ordered for the child. The bottle of Lanoxin contains .05 mg of Lanoxin in 1 ml of solution. What amount should the nurse administer to the child?

Correct Answer: B

Rationale: To calculate the amount of Digoxin to administer, we use the formula: Dose ordered (0.12 mg) / Dose on hand (0.05 mg) x Volume on hand (1 ml) = Volume to administer 0.12 / 0.05 x 1 = 2.4 ml Therefore, the nurse should administer 2.4 ml of Digoxin to the child. Choice B is correct because it accurately calculates the correct volume based on the dosage ordered and the concentration of the solution. Choice A, C, and D are incorrect as they do not calculate the correct volume based on the dosage and concentration provided in the question.

Correct Answer: B

Rationale: The correct answer is B: Pulmonary embolism. Norma's symptoms of chest tightness, shortness of breath, tachypnea, and decreased consciousness are classic signs of a pulmonary embolism, which is a blockage in one of the pulmonary arteries in the lungs. These symptoms are due to a sudden obstruction of blood flow to the lungs, leading to impaired oxygen exchange and potentially life-threatening consequences. A: Asthma attack is incorrect because although asthma can present with chest tightness and shortness of breath, it typically does not cause a decreased level of consciousness. C: Respiratory failure is incorrect because it is a broad term that describes the inability of the respiratory system to adequately oxygenate the blood and remove carbon dioxide. It does not specifically point to the sudden onset of symptoms described in the scenario. D: Rheumatoid arthritis is incorrect because it is a chronic autoimmune disease that primarily affects the joints, and it does not present with the acute respiratory symptoms and decreased

Correct Answer: C

Rationale: The correct answer is C: Kidneys' excretion of sodium and water. When the kidneys excrete sodium and water, the blood volume decreases, leading to a drop in blood pressure. Excretion of excess sodium helps to reduce fluid retention, which can contribute to hypertension. Retention of sodium and water (B) would increase blood volume and blood pressure. Excretion of sodium only (A) would not address the issue of fluid retention. Retention of sodium and excretion of water (D) would not effectively reduce blood volume and lower blood pressure.

Correct Answer: A

Rationale: The correct answer is A because providing the wife with the number of a crisis center offers immediate help and support in a dangerous situation. This step is crucial in ensuring her safety and connecting her with professionals trained to assist in abusive situations. Choice B is incorrect as leaving an abusive partner can be a complex and dangerous process that requires careful planning and support. Choice C is incorrect as discussing the situation with family may not always be safe or helpful, as they may not understand the seriousness of the abuse or may inadvertently put the wife at risk. Choice D is incorrect as it places blame on the victim rather than addressing the abuser's behavior and providing practical support.

Correct Answer: D

Rationale: Correct Answer: D - Serious violations of age-related norms Rationale: 1. Conduct disorder involves persistent patterns of behavior that violate social norms. 2. Children with conduct disorder often exhibit aggression, deceitfulness, and rule-breaking behaviors. 3. These behaviors are serious violations of age-related norms for typical child development. 4. The other choices are not characteristic of conduct disorder; distractibility, ritualistic behaviors, and preference for inanimate objects are more commonly associated with other disorders such as ADHD, OCD, and autism, respectively.
