For which of the ff conditions would the use of salt tablets be considered?

Correct Answer: A

Rationale: Rationale: - Salt tablets are used for mild deficits of serum sodium to help restore electrolyte balance. - Sodium is crucial for fluid balance, nerve function, and muscle contraction. - Severe deficits of serum magnesium, potassium, and calcium require specific electrolyte replacement therapy, not salt tablets. Summary: - Choice A is correct because salt tablets are used for mild deficits of serum sodium. - Choices B, C, and D are incorrect because they involve severe deficits of different electrolytes that require specific replacement therapy.

Correct Answer: C

Rationale: The correct answer is C: “Be sure to protect your tracheostomy from pollutants such as powders, hair, and chemicals.” This instruction is appropriate because keeping the tracheostomy site clean and free from pollutants is crucial in preventing infections and complications. Powders, hair, and chemicals can lead to irritation and blockages, increasing the risk of infection. Explanation of why other choices are incorrect: A: “Never suction your tracheostomy; you might damage your trachea.” - This is incorrect because suctioning is a necessary part of tracheostomy care to clear secretions and ensure proper breathing. B: “You should not feel bad about the tracheostomy – you should feel lucky to be alive.” - This is incorrect as it does not provide practical instructions for tracheostomy care and may not address the patient's emotional concerns adequately. D: “Your tracheostomy will be cleaned each time you visit your doctor.” - This is

Correct Answer: C

Rationale: The correct answer is C: Auscultate lung sounds. By auscultating lung sounds, the nurse can assess for changes in breath sounds which can indicate improvement or deterioration in the patient's condition. This helps monitor the effectiveness of therapy for a pneumothorax and chest-drainage system. Palpating for crepitus (A) is not directly related to monitoring therapy effectiveness. Documenting sputum color and amount (B) is important but does not specifically monitor therapy effectiveness. Monitoring suction level (D) is crucial but does not directly assess the patient's response to therapy.

Correct Answer: D

Rationale: The correct answer is D. Taking piroxicam with food or an oral antacid can help reduce GI irritation as it can protect the stomach lining. Piroxicam is known to cause GI upset due to its effects on prostaglandin synthesis. Spacing the administration every 4 hours (choice A) may not necessarily prevent GI upset. Using the drug for a short time only (choice B) may not address the immediate concern of GI irritation. Decreasing the piroxicam dosage (choice C) may not be necessary if taking it with food or an antacid can effectively alleviate the GI upset.

Correct Answer: C

Rationale: The correct answer is C: Autoantibodies. In Hashimoto's thyroiditis, the immune system mistakenly attacks the thyroid gland by producing autoantibodies against thyroid proteins such as thyroglobulin and thyroid peroxidase. These autoantibodies lead to inflammation and destruction of thyroid tissue. Antigen-antibody complexes (choice A) are not the main mechanism in Hashimoto's thyroiditis. Viral (choice B) and bacterial infections (choice D) do not directly cause autoimmune destruction of the thyroid in this condition. Autoantibodies targeting the thyroid gland are the key pathogenic factor in Hashimoto's thyroiditis.
