1. A central venous pressure reading of 11cm/H(2)O of an IV of normal saline is determined by the nurse caring for the patient. The patient has a diagnosis of pericarditis. Which of the following is the most applicable?
- A. The patient has a condition of hypovolemia.
- B. Not enough fluid has been given to the patient.
- C. Pericarditis may cause pressures greater than 10cm/H(2)O with testing of CVP.
- D. The patient may have a condition of arteriosclerosis.
Correct answer: C
Rationale: A central venous pressure reading above 10cm/H(2)O may indicate a condition of pericarditis, as the inflammation and fluid accumulation around the heart can lead to elevated pressures. Choices A, B, and D are incorrect. Hypovolemia would typically result in lower CVP readings, not higher. Not enough fluid given would also lead to lower CVP levels. Arteriosclerosis is not directly related to CVP readings in the context of pericarditis.
2. How can light therapy be effective?
- A. overcoming weight problems.
- B. helping with allergies.
- C. use in alternative medical treatments.
- D. working with sleep patterns.
Correct answer: D
Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy is not typically used for overcoming weight problems or helping with allergies, it is specifically known for its benefits in regulating sleep patterns. Therefore, the correct answer is 'working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not commonly utilized for overcoming weight problems, helping with allergies, or as a general alternative medical treatment.
3. For which adverse effect of the block does the postpartum nurse monitor the woman after receiving a subarachnoid (spinal) block for a cesarean delivery?
- A. Headache
- B. Pruritus
- C. Vomiting
- D. Hypertension
Correct answer: A
Rationale: The correct answer is 'Headache.' Postdural headache is a common adverse effect associated with a subarachnoid block due to cerebrospinal fluid leakage at the site of dural puncture. This headache worsens when the woman is upright and may improve when she lies flat. To manage this headache, bed rest and adequate hydration are recommended. Pruritus, vomiting, and hypertension are not typically associated with subarachnoid blocks. Pruritus, nausea, and vomiting are more commonly linked to the use of intrathecal opioids.
4. The PN is caring for a client with diabetes insipidus. The nurse can expect the lab work to show:
- A. elevated urine osmolarity and elevated serum osmolarity.
- B. decreased urine osmolarity and decreased serum osmolarity.
- C. elevated urine osmolarity and decreased serum osmolarity.
- D. decreased urine osmolarity and elevated serum osmolarity.
Correct answer: D
Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.
5. Assessment of the client with an arteriovenous fistula for hemodialysis should include:
- A. inspection for visible pulsations.
- B. palpation of thrill.
- C. percussion for dullness.
- D. auscultation of blood pressure.
Correct answer: B
Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.
