Nurse Roberto is aware that a client who has experienced cardiac arrest is MOST at risk for which of the following imbalances?
- A. Metabolic alkalosis
- B. Metabolic acidosis
- C. Respiratory alkalosis
- D. Respiratory acidosis
Correct Answer: D
Rationale: When a client experiences cardiac arrest, their breathing may become insufficient, leading to inadequate elimination of carbon dioxide (CO2) from the body. With reduced CO2 elimination, the level of CO2 in the bloodstream increases, causing respiratory acidosis. This imbalance is characterized by a decrease in blood pH along with an increase in CO2 levels in the blood, resulting in an acidic environment. Respiratory acidosis is the most common imbalance seen in clients who have experienced cardiac arrest, as impaired gas exchange impacts the body's ability to maintain proper acid-base balance.

The nurse anticipates that the signs and symptoms of BPH do NOT include_________.
- A. frequency of urination
- B. pain on urination
- C. dribbling of urine
- D. hesitancy in starting urination
Correct Answer: B
Rationale: One of the signs and symptoms of Benign Prostatic Hyperplasia (BPH) is not pain on urination. BPH is a non-cancerous enlargement of the prostate gland which can cause urinary symptoms such as frequency of urination, dribbling of urine, hesitancy in starting urination, weak urine flow, feeling of incomplete bladder emptying, and increased urination at night (nocturia). Pain on urination is not typically associated with BPH, and it may suggest other urinary tract issues such as a urinary tract infection or a different medical condition.
A patient presents with chest pain that worsens with inspiration and is relieved by sitting forward. There is also evidence of deep vein thrombosis (DVT) in the lower extremity. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Pulmonary embolism
- C. Pericarditis
- D. Aortic dissection
Correct Answer: B
Rationale: The patient's presenting symptoms of chest pain worsened by inspiration and relieved by sitting forward, with associated DVT in the lower extremity, suggest a high likelihood of pulmonary embolism. Chest pain that worsens with inspiration due to pleuritic involvement is a classic symptom of pulmonary embolism. Additionally, the presence of DVT in the lower extremity represents a risk factor for the development of pulmonary embolism, as clots originating in the deep veins can travel to the pulmonary circulation to cause an obstruction. Patients with pulmonary embolism may also exhibit signs of right heart strain, such as tachycardia, tachypnea, and sometimes hemoptysis.
A patient presents with sudden-onset, painless vision loss in the right eye. Fundoscopic examination reveals a cherry-red spot at the macula and attenuated retinal vessels. Which of the following conditions is most likely responsible for this presentation?
- A. Central retinal artery occlusion
- B. Central retinal vein occlusion
- C. Retinal detachment
- D. Acute angle-closure glaucoma
Correct Answer: A
Rationale: The presentation described with sudden-onset, painless vision loss, a cherry-red spot at the macula, and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). CRAO occurs when the central retinal artery, which supplies blood to the inner retinal layers, becomes occluded. The cherry-red spot is due to the exposure of the underlying choroid, which still appears red as it is not affected by the blockage. Attenuated retinal vessels and a pale retina may also be seen due to ischemia. In contrast, central retinal vein occlusion (choice B) presents with sudden painless vision loss, retinal hemorrhages, dilated retinal veins, and cotton-wool spots. Retinal detachment (choice C) typically presents with flashes, floaters, and a curtain-like shadow across the vision. Acute angle-closure glaucoma (
A patient presents with a thyroid nodule and signs of compression such as difficulty swallowing and breathing. Fine-needle aspiration biopsy reveals a follicular pattern and colloid-filled spaces. Which endocrine disorder is most likely responsible for these symptoms?
- A. Hashimoto's thyroiditis
- B. Graves' disease
- C. Follicular adenoma
- D. Thyroid nodules
Correct Answer: C
Rationale: The patient's presentation of thyroid nodule with compression symptoms like difficulty swallowing and breathing, along with fine-needle aspiration biopsy showing a follicular pattern and colloid-filled spaces, is highly suggestive of a follicular adenoma. Follicular adenomas are benign thyroid tumors that can cause compression symptoms due to their growth and size, leading to pressure on surrounding structures in the neck area. The presence of colloid-filled spaces in the biopsy is characteristic of follicular adenomas.
The unit manager the planning to take her regular official business leave for the year. She has written a letter of recommendation to her Immediate supervisor for her assistant unit manager to assume her position while she is on leave. This is an example of delegation by _____.
- A. rank
- B. succession
- C. authority
- D. authority
Correct Answer: B
Rationale: Delegation by succession involves passing on responsibility and authority to a designated successor when the delegator is temporarily unavailable. In this scenario, the unit manager is planning to take her regular official business leave and has recommended her assistant unit manager to assume her position during her absence. This act follows the principle of succession, where the deputy or next in line is entrusted with the duties and decision-making power of the manager. This ensures a smooth transition of responsibilities and allows the operations to continue efficiently in the manager's absence.
