Nursing Elites

1. One day postoperative, the client complains of dyspnea, and his respiratory rate (RR) is 35, slightly labored, and there are no breath sounds in the lower-right base. The nurse should suspect:

• A. cor pulmonale.
• B. atelectasis.
• C. pulmonary embolism.
• D. cardiac tamponade.

Correct answer: B

Rationale: The correct answer is atelectasis. The absence of breath sounds in the lower-right base is a key finding in atelectasis, which occurs when a portion of the lung collapses. The other symptoms such as dyspnea and increased respiratory rate could be present in various pulmonary conditions. Cor pulmonale is typically associated with chronic lung disease, pulmonary embolism presents with sudden onset dyspnea and chest pain, and cardiac tamponade manifests with Beck's triad of hypotension, distended neck veins, and muffled heart sounds.

2. A mother of a newborn notices a nurse placing liquid in her baby's eyes. Which of the following is an inaccurate statement about the need for eyedrops following birth?

• A. Eyedrops following birth help reduce the risk of eye infection.
• B. Eyedrops are required by law.
• C. Eyedrops will keep the eye moist.
• D. Eyedrops are required by law every 6 hours following birth.

Correct answer: D

Rationale: The correct answer is 'Eyedrops are required by law every 6 hours following birth.' This statement is inaccurate because while laws do require the placement of eyedrops, physicians indicate a specific timeframe for their administration. Choice A is correct because eyedrops following birth do help reduce the risk of eye infection by preventing ophthalmia neonatorum. Choice B is incorrect as it implies that eyedrops are mandated solely by law, without considering medical reasons. Choice C is accurate as eyedrops do help keep the eye moist, preventing dryness and discomfort.

3. A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?

• A. Depressed function of the CNS
• B. Increased blood flow
• C. Decreased venous capacity
• D. Pain relief

Correct answer: C

Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.

4. A 62-year-old female is being seen on a home visit by a nurse. The patient reports she has been taking Premarin for years. Which of the following would indicate an overdose?

• A. Lower extremity edema
• B. Sensory changes in the upper extremities
• C. Increased occurrence of fractures
• D. Decreased peripheral blood flow

Correct answer: A

Rationale: Lower extremity edema can indicate an overdose of Premarin. Premarin, an estrogen hormone replacement therapy, can cause fluid retention leading to edema in the lower extremities. Sensory changes in the upper extremities, increased occurrence of fractures, and decreased peripheral blood flow are not typically associated with an overdose of Premarin.

5. Which physiologic mechanism best describes the function of the sodium-potassium pump?

• A. active transport
• B. diffusion
• C. filtration
• D. osmosis

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
