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 (decreased osmolarity) urine and causing dehydration (elevated serum osmolarity). Choice 3 might be seen in a client with SIADH (syndrome of inappropriate ADH). Choices 1 and 2 generally don't occur- urine and serum osmolarity typically move in opposite directions.

The nurse who was not promoted tells another friend, 'I knew I'd never get the job. The hospital administrator hates me.' If she actually believes this of the administrator, who, in reality, knows little of her, she is demonstrating:
- A. compensation.
- B. reaction formation.
- C. projection.
- D. denial.
Correct Answer: C
Rationale: Projection results in unconsciously adopting blaming behavior. It attributes unacceptable attributes to other people.
A client is 36 hours post-op a TKR surgery, 270 cc's of sero-sanguinous accumulates in the surgical drains. What action should the nurse take?
- A. Notify the doctor
- B. Empty the drain
- C. Do nothing
- D. Remove the drain
Correct Answer: A
Rationale: The physician should be notified if excessive drainage is noted from the surgical site.
The nurse can best communicate to a client that he or she has been listening by:
- A. restating the main feeling or thought the client has expressed.
- B. making a judgment about the client's problem.
- C. offering a leading question such as, 'And then what happened?'
- D. saying, 'I understand what you're saying.'
Correct Answer: A
Rationale: Restating allows the client to validate the nurse's understanding of what has been communicated. It's an active listening technique. Judgments should be suspended in a nurse-client relationship. Leading questions ask for more information rather than showing understanding. Saying 'I understand' communicates understanding, but the client has no way of measuring the understanding.
The nurse should consider which of the following as a possible cause for the symptoms experienced by the client in Question 28?
- A. iron deficiency
- B. folate deficiency
- C. peptic ulcer
- D. iron overload
Correct Answer: A
Rationale: Due to her symptoms of fatigue, shortness of breath, lightheadedness, her gender, and her fad dieting, the cause is most likely iron deficiency.
A person using over-the-counter nasal decongestant drops who reports unrelieved and worsening nasal congestion should be instructed to:
- A. switch to a stronger dose of the medication.
- B. discontinue the medication for a few weeks.
- C. continue taking the same medication, but use it more frequently.
- D. use a combination of medications for better relief.
Correct Answer: B
Rationale: Prolonged use of decongestant drops (3 to 5 days) can lead to rebound congestion, which is relieved by discontinuing the medication for 2 to 3 weeks. Nasal congestion results from dilation of nasal blood vessels due to infection, inflammation, or allergy. With this dilation, there is a transudation of fluid into the tissue spaces, resulting in swelling of the nasal cavity. Nasal decongestants (sympathomimetic amines) stimulate the alpha-adrenergic receptors, producing vascular constriction (vasoconstriction) of the capillaries within the nasal mucosa. The result is shrinking of the nasal mucous membranes and a reduction in fluid secretion (runny nose). Decongestants can make a client jittery, nervous, or restless. These side effects decrease or disappear as the body adjusts to the drug. When nasal decongestants are used for longer than 5 days, instead of the nasal membranes constricting, vasodilation occurs, causing increased stuffy nose and nasal congestion. The nurse should emphasize the importance of limiting the use of nasal sprays and drops. As with any alpha-adrenergic drug (for example, decongestants), blood pressure and blood glucose levels can increase. These drugs are contraindicated and should only be used with extreme caution for clients with hypertension, cardiac disease, hyperthyroidism, and diabetes mellitus.
