Nursing Elites

1. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

2. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

• A. Decreased cardiac output can cause hypoxia to the brain
• B. Mental status changes may be a side effect of the patient's medication
• C. Mitral regurgitation is a complication associated with some neurological disorders
• D. The patient may be confused about his diagnosis

Correct answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

3. Which of these clients is likely to receive sublingual morphine?

• A. A 75-year-old woman in a hospice program
• B. A 40-year-old man who just had throat surgery
• C. A 20-year-old woman with trigeminal neuralgia
• D. A 60-year-old man who has a painful incision

Correct answer: A

Rationale: The correct answer is a 75-year-old woman in a hospice program. Sublingual morphine is commonly used in hospice care because patients may have difficulty swallowing, and intravenous access can be uncomfortable and not ideal for palliative care. Choice B, a 40-year-old man who just had throat surgery, is less likely to receive sublingual morphine as he may be able to swallow, and other pain management options may be more suitable. Choice C, a 20-year-old woman with trigeminal neuralgia, would typically require specific medications targeting neuropathic pain rather than sublingual morphine. Choice D, a 60-year-old man with a painful incision, may benefit from localized pain relief or other systemic pain management options, but sublingual morphine is not usually the first choice for this type of pain.

4. The parents of an infant who underwent surgical repair of bladder exstrophy ask if the infant will be able to control their bladder as they get older. How should the nurse respond?

• A. Your child will need catheterization until bladder control is gained.
• B. Your child will be able to control their bladder like other children.
• C. You should potty train your child at the same time you normally would.
• D. Your child will not have a sphincter mechanism for the first 3 to 5 years, so urine will drain freely.

Correct answer: D

Rationale: Bladder exstrophy is a congenital defect where the infant is born with the bladder located on the outside of the body. Surgical repair typically occurs within the first 1 to 2 days of life. In the following 3 to 5 years post-surgery, urine will drain freely from the urethra due to the absence of a sphincter mechanism. This period allows the bladder to develop capacity as the child grows. Subsequent surgical interventions will be required to establish a functioning sphincter mechanism. Therefore, the correct response is that the child will not have a sphincter mechanism for the first 3 to 5 years, leading to urine draining freely. Options A, B, and C are incorrect as they do not align with the physiological process and management of bladder exstrophy.

5. The pediatric nurse caring for a 3-year-old child with cerebral palsy (CP) prepares a home care teaching plan for the caregivers on discharge. Which items will the nurse include in the teaching plan? (Select one that does not apply.)

• A. Apply splints and braces to facilitate muscle control.
• B. Buy toys that are appropriate for the child's abilities.
• C. Encourage the child to perform self-care tasks.
• D. Use skeletal muscle relaxants for short-term control.

Correct answer: D

Rationale: When developing a discharge teaching plan for a child with cerebral palsy (CP), the nurse should focus on strategies to enhance the child's independence and functional abilities. Choices A, B, and C are appropriate interventions to include in the teaching plan for a child with CP. Applying splints and braces can help facilitate muscle control and improve body functioning. Buying toys that are appropriate for the child's abilities can promote engagement and development. Encouraging the child to perform self-care tasks fosters independence and skill development. However, the use of skeletal muscle relaxants for short-term control is not typically a part of routine care for pediatric patients with CP. These medications are usually reserved for specific situations and are not a standard component of home care teaching plans for children with CP.
